Redistricting

Because Delaware has only one congressional district, congressional redistricting is not necessary. The state legislature draws state legislative district lines. The governor may veto the lines drawn by the state legislature.[7][8]

State law requires that state legislative districts be "insofar as possible, contiguous and bounded by roads, streams and other natural boundaries." Further, state law stipulates that district lines "may not be drawn to unduly favor any person or political party." Because these requirements are statutory, the legislature may amend them at its discretion.[7][8]

On November 2, 2021, Gov. John Carney (D) signed Senate Bill 199 into law, enacting the state's new House and Senate district lines.[9] The Delaware General Assembly previously approved the final House and Senate map proposals on November 1, 2021.[10] The Delaware House of Representatives voted 40-1 in favor of the maps with state Rep. Michael Smith (R) voting against it. The Delaware State Senate approved the maps along party lines with all 14 Democrats in favor and all seven Republicans against.[10] These maps took effect for Delaware's 2022 legislative elections.

Senate elections

Delaware state senators serve 2-4-4 terms, where senators serve one two-year term and two four-year terms each decade. Delaware holds elections for its legislature in even years.

2017

See also: Delaware state legislative special elections, 2017

Partisan control of the Delaware State Senate was on the line in the February 25, 2017, special election, as Democrats and Republicans battled to establish a one-member majority in the chamber. In the November 2016 general election, Democrats’ 12-to-nine majority in the Senate shrunk to 11 to 10, as Republican Anthony Delcollo defeated Democratic Senate President Patricia Blevins in District 7, 50.5 to 49.5 percent. The partisan balance then became deadlocked at 10 to 10 after Democratic Sen. Bethany Hall-Long vacated her District 10 seat to become Delaware’s lieutenant governor. In the Delaware Senate, the lieutenant governor has the power of casting tie-breaking votes, giving Democrats a narrow majority in the interim between Hall-Long’s resignation and the swearing-in of her successor. Democrat Stephanie Hansen's victory in the special election allowed Democrats to regain an 11 to 10 majority in the Senate and to defend their trifecta in the state.
