2018 United States midterm elections were held on Tuesday, November 6, 2018, to elect members of the 115th United States Congress and numerous state and local offices across the United States. The contests included all 435 seats in the United States House of Representatives, 35 of 100 seats in the United States Senate, 39 gubernatorial elections, and a wide array of state legislative and ballot measure contests. The elections occurred in the fourth year of the presidency of Donald Trump and were widely interpreted as a referendum on his administration and the policies of the Republican Party (United States).

Background and Political Context

The political environment before the election featured high polarization around figures and institutions such as Donald Trump, the Republican Party (United States), the Democratic Party (United States), and leaders including Nancy Pelosi and Mitch McConnell. National debates were shaped by events involving the Special Counsel Robert Mueller, the Affordable Care Act controversies, and international issues like trade disputes between the United States and China and diplomatic tensions with North Korea. Economic indicators such as unemployment rates reported by the United States Department of Labor and stock market performance influenced narratives advanced by commentators at outlets including the New York Times, Washington Post, and Fox News. Social movements and advocacy groups such as March for Our Lives (organization), National Rifle Association, and Planned Parenthood mobilized voters, while labor organizations like the AFL–CIO and civil rights groups like the American Civil Liberties Union engaged in voter registration and litigation efforts.

Campaigns and Key Issues

Campaigns foregrounded issues including health care debates surrounding the Affordable Care Act, immigration policies such as those tied to the Deferred Action for Childhood Arrivals program, and judicial confirmations highlighted by the nomination of Brett Kavanaugh to the Supreme Court of the United States. Representative and senatorial contests featured high-profile figures including Amy Klobuchar, Kamala Harris, Ted Cruz, Marsha Blackburn, and Claire McCaskill. Campaign finance and advertising involved organizations like EMILY's List, Club for Growth, and Priorities USA Action, and were shaped by decisions from the Federal Election Commission. Issues of campaign messaging intersected with coverage from CNN, MSNBC, and Breitbart News, while digital campaigning used platforms such as Facebook, Twitter, and YouTube. Grassroots efforts and political action committees reacted to events including the confirmation hearings of Brett Kavanaugh and mass shootings that prompted activism by groups like Everytown for Gun Safety.

Election Administration and Turnout

Election administration responsibilities were handled by secretaries of state and local election boards in states such as Florida, Georgia, Texas, and Pennsylvania. Debates about voting access involved laws like voter identification statutes enacted in states including North Dakota, Wisconsin, and Arizona. Litigation addressing registration and voting deadlines reached courts such as the United States Supreme Court and various United States district courts. Voter turnout reached levels not seen in recent midterms, with analyses referencing data from the United States Elections Project and reporting by the Pew Research Center and Cook Political Report. Early voting surges in swing states such as Michigan, Wisconsin, and Pennsylvania were notable in post-election analyses.

Results and Outcomes

In the United States House of Representatives, the Democratic Party (United States) won a net gain of 41 seats, flipping control from the Republican Party (United States), led to the election of Nancy Pelosi as Speaker-designate. In the United States Senate, the Republican Party (United States) retained and slightly expanded its majority, with key races in states including Florida, Missouri, Indiana, and Texas featuring nominees such as Rick Scott, Josh Hawley, Mike Braun, and Ted Cruz. Gubernatorial outcomes included notable victories by Gavin Newsom in California, Andrew Cuomo in New York, and pickups or defenses in states such as Michigan and Kansas. Several historic firsts occurred with the election of candidates like Ilhan Omar and Rashida Tlaib to the United States House of Representatives, and other members of the cohort of freshman Democratic lawmakers who drew attention in Washington, D.C.

Analysis and Impact

Analysts at institutions such as the Brookings Institution, Heritage Foundation, Center for American Progress, and independent groups including FiveThirtyEight and the Cook Political Report examined turnout patterns, suburban realignments, and partisan swings. The results were interpreted in the context of shifting suburban voters in districts from Pennsylvania to Virginia and demographic trends highlighted by researchers at the Pew Research Center. The House majority enabled Democrats to initiate investigations and oversight into the Trump administration and executive branch appointments, affecting confirmation processes in the United States Senate and prompting legislative and oversight actions involving committees chaired by members such as Adam Schiff and Jerrold Nadler. The midterms influenced strategic planning for the 2020 United States presidential election, shaping both parties' candidate recruitment, fundraising by organizations like ActBlue and WinRed, and policy messaging heading into the 2020 United States elections.

State and Local Races

State legislative contests in chambers across states like Ohio, North Carolina, and Texas affected redistricting power ahead of the 2020 census, with litigation involving plaintiffs and defendants in cases heard in federal courts and state supreme courts. Ballot measures from Florida (restoration of voting rights), Arizona (education funding), and Michigan (redistricting reform) produced varied outcomes that reshaped state policy debates. Mayoral and municipal races in cities such as New York City, Chicago, Los Angeles, and Seattle intersected with local issues and national movements, while county and judicial elections determined local governance and legal landscapes across numerous jurisdictions.
