Ballotpedia:"Game-changers" in the 2012 state legislative elections
While there were 6,015 seats elected in 2012, only a handful ultimately impacted which party controls a state legislative chamber. Because of a number of factors including competitiveness and redistricting, many state legislative seats are virtually decided before voters even head to the polls. Thus, in swing states, it is likely that a select few races dictate which party has the majority after an election.
There were 86 chambers that held elections on November 6, 2012. The following table shows a summary of how each chamber falls in the "game-changer" category.
|Chambers where partisan control faced a possible swing||12||13||2||0||27|

Specific state races
- New Hampshire
- New Mexico
- New York
- North Carolina
- Rhode Island
Alaska State Senate: The State Senate was in the unique position of being equally split between Democrats and Republicans, with each party holding 10 seats. Republicans controlled the redistricting process, increasing the likelihood that they would gain control of the Upper Chamber in 2012. Republicans did ultimately take the majority after the 2012 election with a 13-7 split in the senate.
- In District 13(M) incumbent Bettye Davis defeated Harry Crawford, Jr. in the Democratic primary. The winner, Davis, was defeated by incumbent Anna Fairclough (R) in the general election.
- Incumbent Pete Petersen defeated Lynette Moreno Hinz in the Democratic primary in District 25. The winner, Peterson, was defeated by incumbent Republican Lance Pruitt in the general election.
- In District 33, incumbent Peggy Wilson (R) defeated Patricia Mackey and Agnes Moran. Wilson went on to defeat incumbent Kyle Johansen (I) and challenger Matt Olsen (D) in the general election.
Arizona State Senate: While Republicans held a solid majority at 21-9, there were five incumbent Republicans retiring, compared to three Democrats. With eight of thirty seats open, it was conceivable that Democrats could have taken majority control in the chamber.
In the wake of the primary, it was noted that the Tea Party fervor which erupted in 2010 had subsided somewhat, and the State Senate may have been headed for a more centrist path after the November elections.
Arizona House of Representatives: Heading into the election, Republicans held 40 of 60 seats in the House. In 2012, 14 Republicans retired and eight Democrats retired (one Independent retired as well).
- In the Republican primary for District 13, incumbents John Nelson and Don Shooter were projected to face-off, but Nelson withdrew just before the primary, leaving Shooter unopposed.
- District 16: Incumbent Rich Crandall (R) was opposed by current House member John Fillmore. The race was so close that as of August 29, the race had yet to be called. Eventually, Crandall was named the winner. He was seen as a more moderate Republican when compared to the Tea Party-backed Fillmore. Over $80,000 was poured into the races by Republicans in favor of Crandall.
- The Republican primary in District 1 was particularly unique, given that all three candidates were current members of the state legislature. Incumbents Karen Fann and Andy Tobin were members of the House, while Lori Klein represented Senate District 6 since 2011. No Democrats filed to run in this district, so the two winners of the Republican primary, Fann and Tobin, went into the general election unopposed.
- District 20: This seat was left open by retiring Republican John McComish. House Representative Kimberly Yee (R), Democratic challenger Michael Powell, and well known Independent Doug Quelland were all thought to have a legitimate chance at winning. Quelland was formerly a Republican member of the House and competed with Yee for the conservative vote, which was thought to possibly leave an opening for Powell. In the end, Yee came out as the winner.
- District 18: Democrats had hoped that Iraq war veteran Corey Harris would pose a challenge for Republican incumbents Jeff Dial and Bob Robson in this important swing district. However, Dial and Robson were re-elected comfortably.
Arkansas State Senate: Heading into the election, Democrats held 20 seats and Republicans held 15 seats. With 8 Democrats retiring, the chamber was prime for a potential flip to Republicans.
Arkansas House of Representatives: With 46 of 100 seats in the House, Republicans needed to gain 5 to take control of the chamber, or 4 to split power evenly. In total, 26 Democrats and 10 Republicans retired.
The Arkansas legislature had been in Democratic control since the end of the Civil War, and was the last Southern state to have a Democratic legislature. Small government group Americans for Prosperity heavily invested in races in the state in an effort to flip the chambers.
- District 7: In this open seat, Diana Gonzales Worthen (D) was defeated by Jon Woods (R), who was a member of the House. Woods narrowly defeated incumbent Bill Pritchard in the Republican primary.
- District 11: Republicans sought to pick up this seat and succeeded, as Democrat Robert Thompson ran in District 20. Jimmy Hickey, Jr. (R) defeated freshman legislator Steve Harrelson.
- In district 15, State Rep. David J. Sanders successfully used his name recognition to pick up a seat, as he defeated challenger Johnny Hoyt (D).
- District 19: Senator David Wyatt (D) and Rep. Linda Collins-Smith (R) each attempted to keep a seat in the legislature, but Wyatt was victorious.
- District 35: Linda Tyler represented one of the few seats that Democrats had a chance at gaining to keep control of the chamber. Tyler was a member of the House and was defeated by freshman incumbent Jason Rapert (R).

California State Senate: The Democratic Party held majority control of the California State Senate 25-15 heading into the 2012 elections. They needed to gain two seats in order to achieve a 2/3 supermajority. They held 14 even-numbered seats and were expected to win 12 of the 20 odd-numbered seats, meaning that they just needed one more to hit the 27 seat mark. Three of the odd-numbered seats were rated as toss-ups and determined whether Democrats would gain their supermajority, Districts 5, 27, and 31. District 27 was described as lacking a strong Republican candidate, making it the most likely to be won by Democrats in 2012.
- District 5: Current Rep. Bill Berryhill (R) defeated challenger Leroy Ornellas, and defeated Cathleen Galgiani in the Fall.
- District 5 was projected to be one of the tight races that determined if Democrats would get a super majority. Bill Berryhill (R) defeated incumbent Cathleen Galgiani (D).
- District 27: While the Republican candidate Todd Zink had been raising significantly less money than Democrat Fran Pavley, the newly redrawn district does encompass more conservatives than it did prevously, which made for a very tight race in November. Zink, a prosecutor and Marine Corps Reserve officer, was thought to have a fighting chance at getting the seat, but was defeated by Pavley.
- District 31: Republican Assemblyman Jeff Miller, who has high name recognition, looked to keep a seat for Republicans against Democratic challenger Richard Roth. In early September, this already tight race was further complicated by Steve Clute (D), who came in third in the primary. Despite being a Democrat, he took the unusual step of endorsing Miller, a Republican. Despite this, Roth won.
Colorado House of Representatives: Prior to the election, the House was identified as a chamber that had a highly likelihood of changing partisan control. The split of 33 Republicans and 32 Democrats meant that even one lost seat for Republicans would give Democrats the majority.
- Incumbent Republicans Marsha Looper and Amy Stephens faced off in a primary battle for House District 19. Stephens won, 7,458-5,068.
- District 35: Incumbent Democrat Joyce Foster retired, but in the wake of redistricting this race was not necessarily being "defended" by Democrats, as new rural parts of the district drastically changed the demographics. Republican Larry Crowder successfully picked up the seat.
- District 3: Incumbent Daniel Kagan (D) saw her safely Democratic district wash away with redistricting, but managed to defeat challenger Brian Watson (R), the owner of a local real estate investment company.
- District 34: Incumbent John Soper (D) retired due to term limits. This is a seat that Republicans attempted to pick up, but Jodina Widhalm (R) was defeated by Steve Lebsock (D).
- District 47: Keith Swerdfeger (R) retired, leaving a seat for Democrats to potentially pick up. However, Netto Charles Rodosevich (D) was defeated by Clarice Navarro-Ratzlaff (R) in the general election.
- District 6: The newly created sixth was heavily contested, with two Republicans and three Democrats facing off in the primary. Libertarian party candidate Gwendolyn M. Jones also filed to run in the district. Democrat Andrew W. Staton and Republican Ernesto B. Lopez survived the primary, and faced Jones in the general election. Lopez won.
- District 11: Incumbent Anthony DeLuca (D) faced a challenge from Bryan Townsend. Townsend won, upsetting the 12 year incumbent.
- District 19: Incumbent Joseph Booth and challenger Eric R. Bodenweiser faced off in the Republican primary. Bodenweiser won.
- District 22: In a year in which the House looked to be generally uncompetitive, this race was one of the most closely watched. Incumbents Nick T. Manolakos and Joseph Miro faced off in the Republican primary, a race which pitted two well known friends against each other. On election day, Manolakos stated, "We have been friends a long time. We ran a positive campaign. I am glad we didn’t get sidetracked with negativity." In a surprising turn, the low voter turnout led to a rather one sided victory for Miro, who took 61% of the vote, winning 977-630.
Florida State Senate: The Senate, with a composition of 28 Republicans to 12 Democrats heading into the election, was not projected to change hands in 2012.
Florida House of Representatives: Like the Senate, the House had an overwhelming Republican majority (81 of 120 seats); the chamber was expected to remain in Republican control.
- In District 34, Mike Lameyer will attempted to beat out freshman incumbent Ellyn Bogdanoff, but fell short.
- District 100: Incumbent Joseph Gibbons a Democrat elected in 2006, defeated challenger Sheldon Jacob Lisbon.
- District 107 incumbent Luis Garcia retired, which left incumbent Democrats John Patrick Julien and Barbara A. Watson to face each other. Watson narrowly won by 26 votes.
- District 116: Republicans Jose Felix Diaz and Ana Rivas Logan, both incumbents who assumed office in 2012, faced off on August 14. Dias won, 7,818-4,026.
- District 8: This open seat saw large amounts of outside money pour in, and was expected to be one of the closest in the entire Senate. Frank T. Bruno, Jr. (D) was defeated by Dorothy L. Hukill (R).
- District 34: Incumbents Maria Sachs (D) and Ellyn Bogdanoff (R), both freshman, will vied for a seat. Sachs won.
- District 30: New redistricting maps meant that Republican Scott Plakon's once safe district became a tossup. Democrat Karen Castor Dentel successfully flipped the seat, and defeated Plakon.
Georgia State Senate: Heading into the election, the Senate was solidly Republican and was not expected to change hands.
Georgia House of Representatives: Of the 180 seats in the House, Republicans held 115, Democrats held 63, one was vacant, and one was held by an Independent.
- District 7: Tyler Harper defeated State Representative Mark Hatfield and Rodney Vickers for the seat being vacated by Greg Goggans (R). Harper will now face off against Democratic candidate Gene Mitchell in the general election.
- District 15: Incumbent Ed Harbison, who first assumed office in 1992, rebuffed a challenge in the Democratic primary from Reginald Pugh. This election marks the third time Harbison defeated Pugh in a Democratic primary for the seat; this match-up also occurred in 2006 and 2008. Harbison will advance to the general election to take on David Brown.
- District 18: Incumbent Cecil Staton is locked in a close race with Spencer Price in the Republican primary. Only about 200 votes separated the candidates, with the advantage going to Staton, with 98 percent of precincts reporting. Late in the campaign, Price filed an ethics complaint against Staton, alleging that Staton participated in, and benefited from, a conspiracy to divert funds from the Georgia Republican Senatorial Trust to his campaign.
- District 25: Incumbent Johnny Grant, who first joined the Senate in 2005, was defeated by challenger Burt Jones. Jones will face Democratic candidate Darrell Black in the general election.
- District 26: Incumbent Miriam Paris, who first assumed office in 2011, was forced into a runoff by challenger David E. Lucas, Sr. in the Democratic primary. A third candidate in the primary, Irvin Martinez, fell well short of advancing to the runoff. The Democratic nominee will face Republican Bobby Gale.
- District 27: Incumbent Jack Murphy, who first assumed office in 2007, barely survived a primary challenge from Steve Voshall, defeating him by only about 120 votes in the first count. Barring a recount or changes in the results, Murphy will face no opposition in the fall and keep his seat.
- District 31: Incumbent Bill Heath, who first assumed office in 2005, was forced into a runoff by challenger Bill Carruth, with fellow contender J.K. Rogers finishing a distant third. No Democratic candidate is running for this seat.
- District 35: Incumbent Donzella James, who first assumed office in 1993, fended off challenges from Detrius Hill Jones and Cory J. Lynch, and will now face Republican Benjamin Brooks in the general election.
- District 38: Incumbent Horacena Tate, who first assumed office in 1998, defeated Reginald Crossley in the Democratic primary and now faces no opposition in the general election.
- District 44: Incumbent Gail Davenport, who first assumed office in 2011, could be forced into a primary runoff with Gail Buckner. Marcus E. Davis trails in the three way race, which will likely decide who holds the seat for the next two years.
- District 55: Incumbent Gloria Butler, who first assumed office in 1998, defeated Mark Williams in the Democratic primary and does not face major party opposition in the general election.
- District 1: The open seat drew attention from three candidates, John Deffenbaugh, Mike Nowlin, and Alan Painter, who battled for the nomination in the Republican primary. No candidate managed to obtain more than 50 percent of the vote necessary to win the nomination, resulting in a runoff election between the top two vote getters, John Deffenbaugh and Alan Painter. The winner of the runoff primary on August 21st will take on Democratic candidate Thomas McMahan in the general election.
- District 4: Three Republican candidates battled for the open seat. Bruce Broadrick defeated Dennis Mock, and David W. Renz in the primary. No Democratic candidates filed to run in either the primary or general, so Broadrick is almost guaranteed the District 4 seat.
- District 9: Republican candidate Kevin K. Tanner defeated Clint Smith to win the open seat.
- District 28: Republican candidates and top vote getters Dan Gasaway and Jon Heffer will face off in a runoff election to decide the seat.
- District 41: Diana Eckles and Michael Smith will face off in a runoff election to decide the Democratic candidate who will advance to the general election to take on Republican candidate Phil Daniell.
- District 62: Marvin Arrington and Ladawn Blackett Jones will advance to the runoff election to decide the district seat.
- District 66: Bob Snelling and Michael Miller will advance to the runoff election to decide the winner of the Republican nomination. The winner will face Kimberly Alexander (D) in the general election.
- District 92: Tonya P. Anderson and Doreen Williams will advance to the runoff election to decide the district seat.
- District 113: Sharon Sawyer and incumbent Pam Dickerson will advance to a runoff election and will decide the district seat. Dickerson has served in this office since 2011.
- District 139: Patty Bentley and Thomas Coogle will face off in the runoff election to decide the winner of the district seat.
- District 167: Jeff Chapman defeated John Tuten, and will replace Roger Lane (R) in the District 167 seat. Lane vacated the seat for a Superior Court judgeship in the Brunswick Judicial Circuit. Chapman previously represented the 3rd District of the Georgia State Senate from 2005-2011.
- Incumbent Democrat Annazette Collins and activist Patricia Van Pelt Watkins faced-off in a heated primary battle for Senate District 5, with Watkins ultimately emerging victorious. They first met in the February 2011 primary election to replace Rickey Hendon Incumbent Collins was defeated, 10,081 - 8,761.
- District 62: This suburban swing district was closely contested by incumbent Sandy Cole (R) and challenger Sam Yingling (D), with Yingling ultimately winning election.
Iowa State Senate: With a slim Democratic majority of 26-24, the Iowa Senate was identified as a chamber that could have flipped in 2012. With eight incumbents retiring (16% of the chamber, with an equal number from each party retiring, at 4 apiece), there are numerous seats that could potentially be picked up by either party. As a result of Iowa's unique redistricting process, the new map did not greatly harm or help either party, although some have suggested that it may have modestly favored Democrats. The plan passed by a 48-1 margin in the State Senate and a 90-7 margin in the House, lending credence to the belief that Iowa's process was less overtly partisan than redistricting in other states.
Iowa House of Representatives: Republicans had a comfortable 59-40 majority in the House, meaning that Democrats would have needed to flip 11 seats to regain power. However, a complicating factor may have been the higher number of retiring Republicans, 13, to Democrats, 5.
- In District 39, incumbent Erik Helland (R) was defeated by challenger Jake Highfill in a tight race. Highfill prevailed by only 50 votes.
- Incumbents Pat Grassley and Annette Sweeney faced each other in a Republican primary contest that saw Grassley win 2,506-1,588.
- District 4: Democrat Bob Jennings and Republican Dennis Guth were in a tight race for the newly created 4th District. They disagreed sharply primarily over social issues, with Guth going so far as to state that the legalization of same-sex marriage in Iowa was the issue which drove him to seek public office. He supported an effort to unseat the Iowa Supreme Court Justice, David Wiggins, who cast a vote legalize. Guth defeated Jennings in the general election.
- District 49: Even though this is an odd numbered district, it is on the ballot as a result of redistricting. Rita Hart (D) defeated Andrew Naeve (R), a 2010 candidate who only narrowly lost his in the last election.
- In District 13, incumbent Democrat Chris Hall defeated District 1 incumbent Republican Jeremy Taylor.
Kentucky State Senate: Heading into the election, the State Senate majority was held by Republicans, with 22 of 38 seats. Democrats needed to flip 5 seats to gain control of the chamber. Three Republicans retired in 2012.
Kentucky House of Representatives: While Republicans held a majority in the Senate, they were in the minority in the House. Democrats held a relatively healthy 58-41 advantage, meaning that 9 seats would have had to change hands for them to lose the chamber. There was one vacancy heading into the election.
- District 23: Incumbent Jack Westwood (R) did not run for re-election, leaving the seat open. Democrat James Noll was defeated by Republican Chris McDaniel on November 6.
- No Incumbents were set to face each other in the general election, so the most competitive races were expected be in districts in which incumbents have retired and there were two major party candidates, primarily districts 2, 3, 4, 5, and 36.
Kansas State Senate: With a composition of 32 Republicans and 8 Democrats, it was highly unlikely that the Senate would change hands. However, there were several competitive Republican primary battles that emerged in the wake of redistricting.
Seven moderate Republican incumbents were defeated by more conservative rivals in an effort to oust members of the Senate who were hostile to parts of Gov. Sam Brownback's agenda. This fits in with a larger 2012 narrative nationwide in which moderates from both parties are struggling to keep their seats.
Kansas House of Representatives: Like the Senate, it was unlikely that the House would swing to Democratic control. However, there were five districts with Republican primary battles between incumbents, and one district where incumbent Democrats fought to maintain a seat.
- Due to redistricting, District 14 was open. Two House Republicans, John Grange and Forrest Knox, faced off in the August 7 primary. Knox came out victorious.
- District 15: Incumbent Jeff King (R) faced a primary challenge from Dwayne Umbarger (R). Umbarger was placed into King's district after the 2010 census prompted redistricting in Kansas. King successfully held his seat.
- District 61 had a relatively crowded primary Republican field featuring incumbents Richard Carlson and Trent LeDoux, as well as challenger Daniel A. Brenner. Carlson beat out his opponents.
- District 76 featured an unusual Republican primary in which three incumbents faced off: Peggy Mast, elected in 1996, Bill Otto, elected in 2004, and William Prescott, elected in 2008. The longest serving of the three, Mast, won.
- District 86: Veteran Democrats Judith Loganbill and Jim Ward challenged each other in the primary on August 7, and Ward was the winner.
- Republican Anthony Brown survived his primary challenge from James C. "J.C." Tellefson, but was defeated by Democrat Tom Holland in the general election.
- Veteran incumbent Ralph Ostmeyer (R) survived s a primary challenge from John E. Miller. He defeated incumbent Allen Clark Schmidt (D), who was appointed to the seat in February 2011.
- Democrat Nile Dillmore and Republican Brenda Landwehr faced no opposition in their respective primaries, and Dillmore was victorious in the general election on November 6.
- Incumbent Kyle D. Hoffman (R) survived a primary battle from Terry Nunemaker. Hoffman won the Republican nomination, he defeated incumbent Democrat Vincent Wetta in the general election.
Maine State Senate: Democrats needed to flip three seats to gain control of the chamber. The potential for that to happen existed largely due to term limits - 13 of 35 incumbents (37%) were retiring or running for a higher office in 2012.
Maine House of Representatives: 52 (34%) of incumbents retired, most due to term limits. Democrats needed to gain four seats to get control of the chamber.
The Democratic Legislative Campaign Committee identified five races that they would target and assist in funding so that Democrats can retake both chambers, including House districts 128 and 139, as well as Senate districts 17, 25, and 32. The DLCC is primary financed by labor unions.
- District 3: Term-limited State Rep. John Tuttle (D) defeated Bradford Littlefield (R) for this open seat.
- District 27: State Rep. Herbert Clark (D) was defeated by incumbent Senator Douglas Thomas (R). Clark claimed that Thomas was "in hot water in his district" due to an unpopular proposed highway project that passes through the district.
- Assistant Democratic Leader Teresea Hayes defeated Republican challenger Timothy Turner. Hayes narrowly kept her seat in 2010, escaping with a 2,122 - 2,012 over Ryan Lorrain.
- District 128: Republican Heather Sirocki faced a stiff challenge from Jean-Marie Caterina (D), but survived unscathed.
- District 139: In a rematch from 2010, Joseph Wagner (D) was defeated by incumbent Aaron Libby (R).
Massachusetts State Senate and Massachusetts House of Representatives: Both the Senate and the House were overwhelmingly Democratic, and based upon candidate filing lists, neither chamber were expected to flip in 2012.
- First Bristol and Plymouth District: Freshman incumbent Michael J. Rodrigues (D) defeated David P. Meade, Jr..
- The First Essex District is newly created and has no incumbent. Democrats Timothy J. Coco, Kathleen A. O'Connor Ives, and William M. Manzi, III vied for their party's nomination, while Republicans Sam S. Meas and Shaun P. Toohey faced off. O'Connor-Ives came out on top in the Democratic race, while Toohey took the Republican nomination.
- Second Essex District: Incumbent Frederick Berry (D) did not seek re-election. Democrats Edward J. Carroll, Joan B. Lovely, Mary-Ellen Manning and John P. Slattery attempted to take his seat. Lovely won.
- Second Essex and Middlesex District: Republican incumbent Paul Adams narrowly defeated Alex J. Vispoli.
- Plymouth and Barnstable District: President of the Senate Therese Murray soundly defeated challenger Stephen Michael Palmer.
- Second Barnstable District: Demetrius Atsalis (D) faced a challenge from Brian Mannal. In one of a few upsets of the night, Mannal defeated the incumbent.
- Seventh Bristol District: Kevin Aguiar (D) was challenged by Alan Silvia. Aguiar is currently losing by 7 votes, and the race will go to a recount.
- Second Franklin District: Freshman Democrat Denise Andrews fended off challengers Rebecca Bialecki, Genevieve Fraser, and Jim White.
- Second Hampden District saw a Republican primary rematch between Marie Angelides and Enrico John Villamaino, III. Angelides was victorious in 2010, but lost to Democrat Brian Michael Ashe in the general election. Once again, Angelides was victorious in the primary, and will face Ashe in November.
- The Twenty-Fourth Middlesex District is open due to the retirement of William Brownsberger, leaving Margaret Hegarty, Robert Paul Reardon, Jr., and David M. Rogers to compete for the Democratic nomination for the seat. Rogers won.
- Twenty-Fifth Middlesex District: Incumbent Alice Wolf (D) did not running for re-election. Marjorie Decker, Gayle Johnson and Lesley Rebecca Phillips challenged each other for the seat, with Decker garnering a plurality of the votes.
- Tenth Norfolk District: James Vallee resigned in June 2012, leaving the seat open. Two Democrats and three Republicans are vied for the seat. Democrat Jeffrey Roy and Republican Richard Eustis will face off in November.
- One of the closer races was expected to be between incumbent Democrat Kenneth Donnelly and Republican challenger Gerry Dembrowski in the Fourth Middlesex District. Donnelly won.
- Second Hampden District: This district saw a rematch between challenger Marie Angelides and incumbent Brian Michael Ashe. Ashe won for the second time in as many elections.
Michigan State Senate: The Senate did not hold elections in 2012.
Michigan House of Representatives: 18 incumbents retired in 2012, 9 Republicans and 9 Democrats. Republicans held a 63 to 47 majority, and the chamber was unlikely to switch control in 2012.
- District 4: Rose Mary Robinson beat out ten other challengers in the Democratic primary.
- District 40: Michael D. McCready narrowly won with only 32% of the vote, with runners-up David W. Potts and David Wolkinson each garnering 30%.

- District 76: Winnie Brinks (D) sought to capitalize on the same election rigging scheme that was embroiling Speaker Bolger, as she defeated Roy Schmidt (R) who defected to the Republican party just before the primary.
State Senate: Republicans won control of the Senate after the 2010 election. The new redistricting maps could have given the advantage to the DFL (Democrats), according to a report in the Minnesota Post. A total of 16 incumbent senators were paired together and there were eight open seats with no incumbent. DFL State Chair Ken Martin said that a party analysis of the new Senate districts indicates that the partisan lean of the 67 districts was 34-33 in favor of the DFL. However, an analysis by The Pioneer Press indicated a partisan lean of 36-31 for Republicans.
State House: Republicans won control of the House after the 2010 election. The new redistricting maps may have given the advantage to the DFL (Democrats), according to a report in the Minnesota Post. A total of 30 incumbent representatives were paired together and there were 15 open seats with no incumbent. DFL State Chair Ken Martin said that a party analysis of the new Senate districts indicates that the partisan lean of the 67 districts was 73-61 in favor of the DFL. A similar analysis by The Pioneer Press indicated an identical result if the results were strictly based on party-line voting.

New Hampshire House of Representatives: The redistricting process, while controlled by Republicans, eliminated many multi-member districts and left a great deal of uncertainty when creating general election projections. Additionally, the forecasting process was further complicated by the volatile nature of recent politics in the state. Prior to the 2010 elections, Democrats held a 216-174 advantage. Just a single election cycle later, Republicans controlled the House 298-102.

- District 27: Brad M. Hoylman, Thomas M. Greco, and Tanika Inlaw faced off in the Democratic primary.
- District 31: State Rep. Guillermo Linares (D) is challenging incumbent Senator Adriano Espaillat (D). Espaillat unsuccessfully challenged Rep.
