The 2010 United States state legislative elections were held on November 2, 2010, halfway through President Barack Obama's first term in office. Elections were held for 88 legislative chambers, with all states but Louisiana, Mississippi, New Jersey, and Virginia holding elections in at least one house. Kansas and New Mexico held elections for their lower, but not upper houses. Four territorial chambers in three territories and the District of Columbia were up as well. The winners of this election cycle served in their respective legislatures for either two or four-year terms, depending on state election rules.
Owing to the slow recovery from the Great Recession, the unpopularity of Democratic president Barack Obama, and the highly publicized and chaotic passage of the Affordable Care Act, Republicans scored record gains. They net a total of 680 seats and took control of 20 legislative chambers, while the Democrats lost 21 chambers.
The Republican victories gave the party unprecedented power over the redrawing of congressional and state legislative districts following the 2010 census. They also used their newfound majorities to pass conservative legislation in a number of states, weakening labor unions, cracking down on illegal immigration, restricting abortion access, cutting taxes, and reducing government regulation.

The 2010 elections were held during the middle of President Barack Obama's first presidential term. Obama had taken office during the Great Recession, and signed several laws meant to counteract it, including the American Recovery and Reinvestment Act of 2009. He also passed significant healthcare reform through the Affordable Care Act, a highly-controversial effort that a majority of Americans disapproved of at time.Rasmussen Scott Schoen Doug March 9, 2010 Why Obama Can't Move the Health-Care Numbers https://www.wsj.com/articles/SB10001424052748704784904575111993559174212 https://web.archive.org/web/20150402002455/https://www.wsj.com/articles/SB10001424052748704784904575111993559174212 April 2, 2015 March 20, 2025 The Wall Street Journal News Corp 0099-9660 781541372 Other significant issues included illegal immigration and terrorism.

Summary table
Regularly scheduled elections were held in 88 of the 99 state legislative chambers in the United States; nationwide, regularly scheduled elections were held for 6,064 of the 7,383 legislative seats. Most 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. The chambers that were 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 election years.
Note that this table only covers regularly scheduled elections; additional special elections took place concurrently with these regularly scheduled elections.

Electoral predictions
Analysts predicted a very strong showing for the Republicans, anticipating a nationwide wave election in their favor. This was attributed to the nation's slow recovery from the Great Recession, the chaotic passage and implementation of the Affordable Care Act, immigration, and the large number of legislative chambers and governorships that Democrats controlled after the 2006 and 2008 elections.Jacobson Louis July 7, 2010 2010 State Legislatures: Democrats Buckle Up for Wild Ride http://www.governing.com/blogs/politics/2010-state-legislatures-democrats-wild-ride.html dead https://web.archive.org/web/20100728141936/http://www.governing.com/blogs/politics/2010-state-legislatures-democrats-wild-ride.html July 28, 2010 July 15, 2024 Governing As the campaign progressed, Democratic prospects only became worse, leading to the largest gap in legislative chambers held by each party considered vulnerable in over a decade.Jacobson Louis September 29, 2010 2010 State Legislatures: Forecast Worsens for Democrats http://www.governing.com/blogs/politics/2010-state-legislatures-forecast-worsens-democrats.html dead https://web.archive.org/web/20101205232729/http://www.governing.com/blogs/politics/2010-state-legislatures-forecast-worsens-democrats.html December 5, 2010 July 15, 2024 Governing By election day, Republicans were expected to be able to flip between eleven and twenty seven legislative chambers from Democrats, with only one Republican-held chamber considered vulnerable.

Impact
The massive Republican gains made in 2010 immensely strengthened their position on the national stage. This had both short-term effects, such as their ability to counter the policies of president Barack Obama, as well as long term consequences due to the impending redistricting cycle. In the short term, these elections heralded in a conservative shift in state legislatures across the country, especially in the states where Republicans gained complete control. This led to a tightening of policies surrounding abortion and illegal immigration, a loosening of tax policy, and the curtailing of the power of labor unions. Many of these states refused to accept the Medicaid expansion offered by the Affordable Care Act meant to close the Medicaid coverage gap.Greenfield Jeff May 12, 2021 We’re still feeling the aftershocks of the 2010 midterm elections https://www.washingtonpost.com/outlook/2021/05/12/2010-elections-politics-effects/ live https://web.archive.org/web/20210615075638/https://www.washingtonpost.com/outlook/2021/05/12/2010-elections-politics-effects/ June 15, 2021 February 3, 2025 The Washington Post

For the past several years, immigration policy had become an increasingly-important issue in state legislatures.Couch Aaron March 23, 2011 State illegal immigration laws: What have they accomplished? https://www.csmonitor.com/USA/Politics/2011/0323/State-illegal-immigration-laws-What-have-they-accomplished 2025-04-22 Christian Science Monitor 0882-7729 In April 2010, the Arizona legislature passed Arizona SB 1070, which was considered at the time to be the strictest anti-illegal immigration bill in the country.Archibold, Randal C. April 24, 2010 U.S.'s Toughest Immigration Law Is Signed in Arizona https://www.nytimes.com/2010/04/24/us/politics/24immig.html The New York Times 1 Following the 2010 elections, a number of states, some of which had just become Republican-controlled, passed measures in the same vein as the Arizona law. The most controversial among these was Alabama HB 56, which gave police wide discretion to detain those they suspected of being undocumented immigrants, banned undocumented immigrants from receiving any public benefits, including attending public universities, and required public schools to enquire about the immigration statuses of their students.Fausset Richard June 10, 2011 Alabama enacts anti-illegal-immigration law described as nation's strictest https://www.latimes.com/nation/la-xpm-2011-jun-10-la-na-alabama-immigration-20110610-story.html August 27, 2011 Los Angeles TimesGargis Peggy 2011-06-09 Alabama gov. signs nation's toughest immigrant law https://www.nbcnews.com/id/wbna43343494 2025-04-22 NBC News en The immigration laws passed in both Alabama and Georgia received heavy criticism for their potentially devastating impacts on state agriculture, where many farmers relied on immigrant labor to harvest their crops.Pilkington Ed 2011-10-14 Alabama immigration: crops rot as workers vanish to avoid crackdown https://www.theguardian.com/world/2011/oct/14/alabama-immigration-law-workers 2025-04-22 The Guardian en-GB 0261-3077Chappell Bill 2011-05-27 Georgia Farmers Say Law Keeps Migrant Workers Away https://www.npr.org/sections/thetwo-way/2011/05/27/136718112/georgia-farmers-say-immigration-law-keeps-workers-away 2025-04-22 NPR en Many of the strictest portions of these laws were later blocked by federal courts.Winograd Ben 2012-08-21 Alabama Ruling Yet Another Rebuke to State Immigration Laws https://immigrationimpact.com/2012/08/21/alabama-ruling-yet-another-rebuke-to-state-immigration-laws/ 2025-04-22 Immigration Impact en-US
The direct impact of the enforcement of these laws was often minimal, with many such as Arizona SB 1070 producing no arrests in its first few months on the books. The widest-reaching effects of these laws, however were social: changing attitudes of both immigrants and citizens. Some viewed the new laws as passed both in response to the backlash to the recent rise in illegal immigration as well as further fueling said backlash. Opponents of these laws criticized them as "Juan Crow" laws which created a climate of fear in immigrant populations.Garcia Uriel J.

Southern, rural Democratic fall
Democrats had been slowly losing ground in the rural South for the past several decades leading up to the 2010 elections. Democrats lost nearly every southern legislative chamber up for election in 2010, with White, rural incumbents primarily falling victim. Republicans successfully tied the conservative Democrats in these seats to the more liberal national party, eroding their local support and tying them to policies unpopular in their districts. A number of incumbents who survived would later switch to the Republican party, with many doing so before or immediately after the election. This left most Southern Democratic caucuses primarily made up of African American and Hispanic legislators, often based in urban areas, with a nearly extinct White, rural caucus, and a weakened but slowly growing suburban caucus.Martin Jonathan 2010-11-28 Democratic South finally falls https://www.politico.com/story/2010/11/democratic-south-finally-falls-045627 2025-02-03 POLITICO en By 2014, Republicans controlled every governorship, U.S. Senate seat, and legislative chamber in the Deep South.Rogers Alex 2014-12-07 Landrieu's Loss a Harsh Milestone for Southern Democrats https://time.com/3621999/mary-landrieu-southern-democrats/ 2025-02-03 TIME en

Bolstered by heavily gerrymandered legislative maps, the 2010s saw a sharply-conservative turn in Midwestern state policy.
