2018 elections
Choose a chamber below:


Republicans maintained a majority in the Oklahoma State Senate in the November 6, 2018 elections. A total of 24 seats out of the chamber's 48 seats were up for election in 2018.[1] Heading into the election, Republicans controlled 38 seats to Democrats' eight, with two seats vacant. After the election, Republicans had a 39-9 majority.

The Republican Party maintained a trifecta after the 2018 elections, keeping control of the state Senate, state House, and governorship.

Because state senators in Oklahoma serve four-year terms, winning candidates in this election served through 2022 and played a role in Oklahoma's redistricting process. In Oklahoma, congressional and state legislative district boundaries are drawn by the state legislature. If the legislature is unable to approve a state legislative redistricting plan, a backup commission must draw new lines. Read more below.

The Oklahoma State Senate was one of 87 state legislative chambers with elections in 2018. There are 99 chambers throughout the country.

Oklahoma state senators serve staggered, four-year terms and half of the Senate is up for election every two years.

Process to become a candidate

See also: Ballot access requirements for political candidates in Oklahoma

DocumentIcon.jpg See statutes: Title 26, Chapter 5 of the Oklahoma Code

Filing

Each candidate must file a declaration of candidacy with the Oklahoma State Election Board to place his or her name on the ballot. The declaration must be filed during the candidate filing period, which begins on the first Wednesday in April and ends on the following Friday. The declaration of candidacy must be signed and notarized and include the following:[5][6][7]

  • the name of the candidate
  • the candidate's address
  • the office the candidate seeks
  • the candidate's date of birth
  • the candidate's political party affiliation
  • the precinct and county where the candidate is a registered voter
  • a sworn oath affirming that the candidate is qualified to become a candidate for the office being sought and to hold that office if elected

A partisan candidate must be a registered voter of the political party with which he or she wishes to run for at least six months immediately preceding the first day of the candidate filing period. An independent candidate must be registered as an independent voter for at least six months before filing as a candidate. A candidate of a new political party that has not been officially recognized for six months must be registered with that party within 15 days following its recognition.[8]

A candidate may file for only one office per election. There is no process for candidates to run as write-ins as write-in voting is not permitted in Oklahoma.[9]

Fees

Each candidate must pay a filing fee to the Oklahoma State Election Board or else file a petition signed by 4 percent of registered voters who will be eligible to vote for the candidate in the election (this figure is determined by using the latest January 15 voter registration report).[10]

Filing fees vary according to the office being sought by the candidate and are described in the table below.[10]

Filing fees
Office sought Filing fee
Governor of Oklahoma $2,000
United States Senator $2,000
United States Representative
Lieutenant Governor
Corporation Commission
Attorney General
State Auditor and Inspector
Superintendent of Public Instruction
Treasurer
Commissioner of Insurance
Commissioner of Labor
$1,000
State Senator $750
State Representative
District Judge or Associate District Judge
District Attorney
$500
County Offices $300

Challenges

Any candidate may challenge another candidate’s candidacy by filing a written petition of contest with the Oklahoma State Election Board. If there is only one candidate running for office, any registered voter who is eligible to vote for that candidate may file a contesting petition. This must be done by 5 p.m. on the second business day after the close of the candidate filing period. The contesting petition must be accompanied by a deposit of $250, which will be returned to the challenger if he or she successfully proves that the candidate does not fulfill all requirements to be a candidate for that office.[11][12][13][14]

Qualifications

Trifectas

A state government trifecta is a term that describes single-party government, when one political party holds the governor's office and has majorities in both chambers of the legislature in a state government. Republicans in Oklahoma gained a state government trifecta as a result of the 2010 elections by taking control of the governor's office.

Impact of term limits

See also: Impact of term limits on state senate elections in 2018 and Impact of term limits on state legislative elections in 2018

The Oklahoma State Senate has been a term-limited state Senate since Oklahoma voters approved State Question 632 in 1990, as an initiated constitutional amendment. This amendment became part of Section 17A of Article V of the Oklahoma Constitution and limits the amount of time that an Oklahoma State Senator can serve to a cumulative total of 12 years in either or both chambers of the Oklahoma State Legislature.

A total of 24 out of 48 seats in the Oklahoma State Senate were up for election in 2018. In the 2018 elections, six senators were ineligible to run because of term limits. The following state senators were term-limited in 2018:

Democratic: (3)

Republicans (3):

Of the 87 state legislative chambers that held elections in 2018, 24 of them—12 senate chambers and 12 house chambers—included incumbents who were unable to run for re-election due to term limits.[18] In the 24 chambers affected by term limits in 2018, 1,463 seats were up for election.[19] The Nevada Senate, Arkansas House, and Arkansas Senate are impacted by term limits, but no incumbents were term-limited in 2018. There are 99 chambers throughout the country.

A total of 271 state legislators—96 state senators and 175 state representatives—were ineligible to run in the 2018 elections because of term limits. This represented 4 percent of the 6,066 total seats up for election in November 2018.[20][21] Republicans had twice as many state legislators term-limited in 2018 than Democrats. A total of 86 Democrats were term-limited, while 177 Republicans were term-limited.

Wave election analysis

See also: Wave elections (1918-2016)

The term wave election is frequently used to describe an election cycle in which one party makes significant electoral gains. How many seats would Republicans have had to lose for the 2018 midterm election to be considered a wave election?

Ballotpedia examined the results of the 50 election cycles that occurred between 1918 and 2016—spanning from President Woodrow Wilson's (D) second midterm in 1918 to Donald Trump's (R) first presidential election in 2016. We define wave elections as the 20 percent of elections in that period resulting in the greatest seat swings against the president's party.

Applying this definition to state legislative elections, we found that Republicans needed to lose 494 seats for 2018 to qualify as a wave election.

The chart below shows the number of seats the president's party lost in the 10 state legislative waves from 1918 to 2016. Click here to read the full report.

Competitiveness

Every year, Ballotpedia uses official candidate lists from each state to examine the competitiveness of every state legislative race in the country. Nationally, there has been a steady decline in electoral competitiveness since 2010. Most notable is that the number of districts with general election competition has dropped by more than 10 percent.

Historical context

See also: Competitiveness in State Legislative Elections: 1972-2014

Uncontested elections: In 2014, 32.8 percent of Americans lived in states with an uncontested state senate election. Similarly, 40.4 percent of Americans lived in states with uncontested house elections. Primary elections were uncontested even more frequently, with 61 percent of people living in states with no contested primaries. Uncontested elections often occur in locations that are so politically one-sided that the result of an election would be a foregone conclusion regardless of whether it was contested or not.

F5 Pop. % with uncontested state legislative races.png

Open seats: In most cases, an incumbent will run for re-election, which decreases the number of open seats available. In 2014, 83 percent of the 6,057 seats up for election saw the incumbent running for re-election. The states that impose term limits on their legislatures typically see a higher percentage of open seats in a given year because a portion of incumbents in each election are forced to leave office. Overall, the number of open seats decreased from 2012 to 2014, dropping from 21.2 percent in 2012 to 17.0 percent in 2014.

Incumbent win rates: Ballotpedia's competitiveness analysis of elections between 1972 and 2014 documented the high propensity for incumbents to win re-election in state legislative elections. In fact, since 1972, the win rate for incumbents had not dropped below 90 percent—with the exception of 1974, when 88 percent of incumbents were re-elected to their seats. Perhaps most importantly, the win rate for incumbents generally increased over time. In 2014, 96.5 percent of incumbents were able to retain their seats. Common convention holds that incumbents are able to leverage their office to maintain their seat. However, the high incumbent win rate may actually be a result of incumbents being more likely to hold seats in districts that are considered safe for their party.

Marginal primaries: Often, competitiveness is measured by examining the rate of elections that have been won by amounts that are considered marginal (5 percent or less). During the 2014 election, 90.1 percent of primary and general election races were won by margins higher than 5 percent. Interestingly, it is usually the case that only one of the two races—primary or general—will be competitive at a time. This means that if a district's general election is competitive, typically one or more of the district's primaries were won by more than 5 percent. The reverse is also true: If a district sees a competitive primary, it is unlikely that the general election for that district will be won by less than 5 percent. Primaries often see very low voter turnout in comparison to general elections. In 2014, there were only 27 million voters for state legislative primaries, but approximately 107 million voters for the state legislative general elections.

Redistricting in Oklahoma

See also: Redistricting in Oklahoma

Because state senators in Oklahoma serve four-year terms, winning candidates in this election served through 2022 and played a role in Oklahoma's redistricting process. In Oklahoma, congressional and state legislative district boundaries are drawn by the state legislature. If the legislature is unable to approve a state legislative redistricting plan, a backup commission must draw new lines.

State legislature districts in the 2010-2012 redistricting process

On May 16, 2011, the state legislature passed a state legislative redistricting plan, which was signed into law by the governor on May 20, 2011. The newly approved Senate district boundaries were challenged in state court, but all challenges were ultimately dismissed.[25]

Pivot Counties

See also: Pivot Counties by state

There are no Pivot Counties in Oklahoma. Pivot Counties are counties that voted for Barack Obama (D) in 2008 and 2012 and for Donald Trump (R) in 2016. Altogether, the nation had 206 Pivot Counties, with most being concentrated in upper midwestern and northeastern states.

In the 2016 presidential election, Donald Trump (R) won Oklahoma with 65.3 percent of the vote. Hillary Clinton (D) received 28.9 percent. In presidential elections between 1904 and 2016, Oklahoma voted for the winning presidential candidate 72.4 percent of the time. In that same time frame, Oklahoma supported Republican candidates for president more often than Democratic candidates, 65.5 to 34.5 percent. The state favored Republicans in every presidential election between 2000 and 2016.

Presidential results by legislative district

The following table details results of the 2012 and 2016 presidential elections by state Senate districts in Oklahoma. Click [show] to expand the table. The "Obama," "Romney," "Clinton," and "Trump" columns describe the percent of the vote each presidential candidate received in the district. The "2012 Margin" and "2016 Margin" columns describe the margin of victory between the two presidential candidates in those years. The "Party Control" column notes which party held that seat heading into the 2018 general election. Data on the results of the 2012 and 2016 presidential elections broken down by state legislative districts was compiled by Daily Kos.[26][27]

In 2012, Barack Obama (D) won 4 out of 48 state Senate districts in Oklahoma with an average margin of victory of 34.6 points. In 2016, Hillary Clinton (D) won 4 out of 48 state Senate districts in Oklahoma with an average margin of victory of 34.6 points.
In 2012, Mitt Romney (R) won 44 out of 48 state Senate districts in Oklahoma with an average margin of victory of 37.9 points. In 2016, Donald Trump (R) won 44 out of 48 state Senate districts in Oklahoma with an average margin of victory of 41.4 points. Trump won three districts controlled by Democrats heading into the 2018 elections.

If an incumbent runs as a write-in candidate, Ballotpedia does not consider them to be retiring. If an incumbent runs in the same chamber for a different seat, Ballotpedia does not consider them to be retiring.
