US Midterm Elections on November 3 to Shape Congress and Trump’s Final Two Years

The United States will hold its midterm elections on November 3, 2026, giving voters an opportunity to reshape the balance of power in Congress halfway through President Donald Trump’s four-year term. The outcome will determine which party controls the House of Representatives and the Senate, with significant implications for the administration’s legislative agenda and oversight.

Unlike a presidential election, the midterm elections do not directly change who occupies the White House. The president remains in office regardless of the results. However, the elections can significantly alter the balance of power between the executive branch and the legislative branch, influencing how easily the president can implement his policies.

How the Midterm Elections Work

The US Congress consists of two chambers: the House of Representatives, the lower chamber, and the Senate, the upper chamber. Congressional elections take place every two years, and elections held halfway through a president’s term are known as midterm elections.

All 435 voting seats in the House of Representatives are contested every two years. House members serve two-year terms and represent congressional districts. Each state’s number of representatives is determined by its population.

The Senate has 100 members, with each of the 50 states electing two senators. Senators serve six-year terms, and approximately one-third of Senate seats are contested every two years. In the 2026 elections, regularly scheduled races for Class II Senate seats will take place alongside certain special elections to fill vacancies.

Who Can Vote?

US citizens aged 18 or older can vote in federal elections if they meet the applicable voter-registration requirements. Green card holders, who are not US citizens, cannot vote in federal elections, although limited exceptions for certain local elections exist in some jurisdictions.

Voter-registration rules vary by state. Some states require voters to register weeks before Election Day, while others permit same-day registration. North Dakota does not require voter registration.

Identification requirements also differ across states. Some require photo identification, while others accept alternative documents or use different verification procedures. Rules governing voting rights for people convicted of serious crimes also vary by state.

US citizens living abroad can vote through absentee-ballot procedures. Overseas voters and military personnel can use the Federal Post Card Application to request voter registration and absentee ballots.

How Candidates Compete

Candidates generally seek their parties’ nominations through primary elections or caucuses before competing in the general election. Primary-election rules differ by state. Some states restrict participation to registered party members, while others allow unaffiliated voters to participate under specified conditions.

Candidates must meet constitutional qualifications and applicable state ballot-access requirements. To serve in the House of Representatives, a candidate must be at least 25 years old, have been a US citizen for at least seven years, and be an inhabitant of the state they seek to represent when elected.

Senate candidates must be at least 30 years old, have been US citizens for at least nine years, and be inhabitants of their respective states when elected.

Voting and Counting Procedures

Americans can vote in person on Election Day, participate in early voting where available, or cast ballots by mail under applicable state rules.

The United States does not have a single national election commission responsible for administering all elections. Instead, state and local election officials oversee polling places, ballot collection, counting and certification according to their respective laws.

Election-night results are preliminary. Officials must complete the required ballot processing, verification, audits and certification procedures before results become final. Mail-in ballots and close contests may also lead to recounts under state law.

Why the Elections Matter for the Trump Administration

The party holding a majority in either chamber of Congress gains substantial influence over that chamber’s leadership, committee appointments, legislative agenda and oversight responsibilities.

In the House, the majority party elects the speaker and exercises considerable influence over investigations and scrutiny of the administration. The Senate, meanwhile, considers presidential nominations for federal judgeships, Cabinet positions and other offices, and plays a central role in considering treaties.

Most legislation must pass both chambers before being sent to the president for signature. If the House and Senate are controlled by different parties, disagreements can make legislation more difficult to pass.

A Democratic majority in either chamber could increase congressional scrutiny of the Trump administration and complicate efforts to advance its policy priorities. If Republicans retain control of both chambers, the administration would generally have a more favorable environment for pursuing its legislative agenda.

However, even if the opposition party wins control of Congress, it cannot automatically remove the president from office. The election will instead help determine the political and legislative conditions under which Trump governs during the final two years of his current term.

The November 3 midterm elections are therefore expected to be a consequential test of the administration’s political standing and a decisive factor in shaping the direction of US domestic policy and congressional oversight through 2028.
