Control of Congress on the ballot
Americans are voting in midterm elections that will determine whether Republicans retain control of Congress or Democrats gain the power to constrain President Donald Trump during the final two years of his second term. The election covers all 435 voting seats in the House of Representatives, 35 Senate seats and 39 governorships, alongside thousands of state and local contests.
Republicans entered election day with narrow room for error in the House. Democrats need a net gain of four seats to take control of the chamber, where members face voters every two years. The Senate map includes 33 regularly scheduled races and special elections in Florida and Ohio. Republicans hold 53 Senate seats, while Democrats and independents aligned with them hold 47, meaning Democrats need four gains for an outright majority.
The congressional result will shape the federal government’s ability to pass legislation and conduct oversight. Both chambers must approve bills, while committees can investigate the executive branch. A divided government could slow the White House agenda and expose the administration to more aggressive scrutiny. Continued Republican control would give Trump a stronger path to advance his programme through Congress.
Only a fraction of House districts are considered genuinely competitive after years of redistricting and political polarisation. Closely watched Senate races include contests in Michigan, Georgia, Maine, Ohio and Texas, with other competitive campaigns in Alaska, Kansas, Iowa, North Carolina and New Hampshire. In a 50-50 Senate, Republican Vice-President JD Vance would cast tie-breaking votes.
Affordability has been a central campaign issue, encompassing food, housing, fuel and healthcare costs. Immigration, abortion rights, voting rules, artificial intelligence, data centres, tariffs and trade have also featured. State races carry their own consequences because governors and legislatures set policy in areas including education, reproductive rights, taxation and election administration.
Midterms have historically been difficult for the president’s party. The party holding the White House has lost House seats in 18 of the past 20 midterm elections, although that pattern is not automatic. Republicans gained seats under George W Bush in 2002, while Democrats under Barack Obama and Republicans during Trump’s first term suffered major House losses.
The election is also being watched for how officials administer voting and certify results. Trump has encouraged supporters to treat the contest as a judgment on his presidency. The immediate question is whether that appeal can overcome the historical midterm penalty and preserve Republican majorities, or whether dissatisfaction with the administration gives Democrats control of one or both chambers.
