The
2022 elections,
midterm elections held under the
presidency of Democrat
Joe Biden, defied conventional expectations. Although Republicans had gained more legislative seats across the country than Democrats, they had lost control of several state legislative chambers. Republican gains were more concentrated in chambers they already controlled, while Democrats made more gains in states they controlled, as well as in
battleground states where
independent or court-ordered
redistricting had dismantled the
Republican-tilted maps of the 2010s. This enhanced Democratic policymaking power at the state level despite Republican
victories at the federal level. Among the states holding regularly-scheduled legislative elections in 2023, Republicans had fully controlled the
Mississippi and
Louisiana legislatures since
2011, while Democrats had controlled the
New Jersey Legislature since
2003. Virginia had a
divided government after Republicans won control of the
House of Delegates in
2021.
Party switching Republicans gained significant clout in two state legislatures prior to the election due to
party switching by incumbent legislators. In both
Louisiana and
North Carolina, party-switching Democrats gave Republicans
supermajorities in each state's House of Representatives which, combined with Republicans' existing supermajorities in each state's Senate, gave the party the ability to override
vetoes of each state's Democratic governors. == Summary table ==
