The 2012 United States state legislative elections were held on November 6, 2012, for 86 state legislative chambers in 44 states. Across the fifty states, approximately 65 percent of all upper house seats and 85 percent of all lower house seats were up for election. Nine legislative chambers in the five permanently-inhabited U.S. territories and the federal district of Washington, D.C. also held elections. The elections took place concurrently with several other federal, state, and local elections, including the presidential election, U.S. Senate elections, U.S. House elections, and gubernatorial elections.

13 chambers shifted party control, as Republicans had gained many chambers in the 2010 mid-term elections, and this was seen as a modest rebalancing.[1]

Democrats won the Colorado House of Representatives, Maine Senate, Maine House of Representatives, Minnesota Senate, Minnesota House of Representatives, New Hampshire House of Representatives, and Oregon House of Representatives that was previously tied. Meanwhile, Republicans won the Wisconsin Senate, which was briefly under Democratic control after multiple recall elections earlier in the year, and both chambers of the Arkansas legislature for the first time since 1874. The Alaska Senate went from a Democratic-led coalition to Republican control. The Washington Senate went from Democratic control to a Republican-led coalition, and the New York State Senate went from Republican control to a Republican-led coalition.

Democrats won a trifecta in Minnesota for the first time since 1991.

Summary table

Regularly scheduled elections were held in 86 of the 99 state legislative chambers in the United States. Nationwide, regularly scheduled elections were held for 6,015 of the 7,383 legislative seats. Many legislative chambers held elections for all seats, but some legislative chambers that use staggered elections held elections for only a portion of the total seats in the chamber.[2] The chambers not up for election either hold regularly-scheduled elections in odd-numbered years, or have four-year terms and hold all regularly-scheduled elections in presidential midterm election years.

Note that this table only covers regularly scheduled elections; additional special elections took place concurrently with these regularly scheduled elections.

Redistricting

See also: 2010 United States redistricting cycle

The 2022 elections were the first held after redistricting following the 2020 census. All states holding elections in 2022 did so under new maps drawn in accordance with the new census results with the exception of Montana and Pennsylvania. Montana implements its new maps four years after the census as opposed to two, whereas Pennsylvania's Supreme Court rejected the legislative maps drawn by the state's politician redistricting commission, leaving the elections to be held under the lines passed in 2001.[3][4] In a majority of states, legislative redistricting is controlled by the state legislature, often subject to gubernatorial veto. This allows for widespread gerrymandering, in which the party in power draws legislative boundaries to favor itself. Many states delegate redistricting power to an independent or bipartisan redistricting commission, often with the goal of minimizing or eliminating partisan gerrymandering.[3]

Electoral predictions

Analysts considered both the Democratic and Republican parties to be at approximately equal risk of losing state legislative chambers to the other, owing to the expectation that this would be the first election that was not a wave election since 2004. Although Republicans were expected to win states like Arkansas, which had been trending towards them in recent years, Democrats had the potential to roll back some of the gains Republicans had made in 2010 in more competitive states such as Colorado. Despite the potential for Democratic gains, they were still expected to remain far behind the Republicans in overall chamber control due to the major losses the party suffered in 2010 and 2011.[5]

Ratings are designated as follows:

  • "Tossup": Competitive, no advantage
  • "Lean": Competitive, slight advantage
  • "Likely": Not competitive, but opposition could make significant gains
  • "Safe": Not competitive at all
