U.S. midterm elections determine who represents Americans in Congress during the second half of a presidential term. They also shape which political party controls the House of Representatives and the Senate, influencing the federal government’s ability to pass legislation, approve spending, and conduct oversight.
The next regularly scheduled federal general election is November 3, 2026, according to the Federal Election Commission (FEC). Although midterm elections receive less international attention than presidential elections, their results can have a substantial effect on national policy.
Understanding the process begins with knowing which offices appear on the ballot, how congressional terms work, and why state election rules matter.
What Are U.S. Midterm Elections?
Midterm elections take place halfway through a president’s four-year term. Presidential elections occur every four years, while congressional elections occur every two years.
Voters do not elect a president during a regular midterm election. Instead, they choose members of Congress and may vote in state and local contests, depending on where they live.
The U.S. Congress has two chambers: the House of Representatives and the Senate. Both participate in the federal lawmaking process, but their membership and election schedules differ.
According to “USA.gov’s guide to midterm elections” (https://www.usa.gov/midterm-elections), congressional elections determine who represents each state in the federal government and help establish which political party holds a majority in each chamber.
Which Seats Are on the Ballot?
The House of Representatives
The House has 435 voting members, with representation allocated among states according to population. Each representative serves a two-year term.
Consequently, all 435 voting House seats are scheduled for election during a regular midterm year. Every congressional district has an opportunity to elect a representative, although the candidates and ballot arrangements differ by district.
House elections can influence legislation, federal spending, committee leadership, and investigations into government agencies.
A change in the party controlling the House can also change which bills receive consideration and which issues receive congressional attention.
The Senate
The Senate has 100 members, with two senators representing each state. Senators serve six-year terms, and their election schedules are staggered.
Approximately one-third of the Senate’s seats are normally scheduled for election every two years. As a result, voters in some states choose a senator during a midterm election, while voters in other states do not have a regular Senate election that year.
Special elections can create exceptions when a Senate seat becomes vacant.
Because senators serve longer terms than representatives, the Senate’s composition changes on a different schedule from the House.
Why Does Control of Congress Matter?
Congress writes federal legislation, approves federal spending, and performs oversight of the executive branch. The House and Senate must often cooperate to pass a bill, so party control can affect which proposals advance.
The party holding a majority in a chamber generally has greater influence over its leadership, committee assignments, and legislative agenda. However, majority control does not guarantee that every proposal supported by that party will become law.
Senate procedure, internal party disagreements, negotiations between chambers, presidential action, and other legal requirements can all affect the outcome.
Congress also has constitutional responsibilities beyond passing bills. Depending on the circumstances, these include impeachment proceedings, confirmation of certain presidential nominees by the Senate, and oversight hearings.
The practical effect of an election therefore depends not only on which party gains seats but also on the margins, the issues being considered, and the willingness of lawmakers to negotiate.
How Do Congressional Candidates Get on the Ballot?
Federal elections are administered through a combination of state and federal rules. States establish many of the procedures governing candidate qualifications, ballot access, voter registration, early voting, absentee voting, and vote counting.
Candidates commonly compete in party primaries or other nomination processes before the general election. The precise process varies by state, and some states use different systems for determining which candidates advance.
A candidate’s name appearing on a ballot is not governed by one identical nationwide procedure for every election. Voters should consult their state election office for rules that apply to their location.
The FEC provides federal election dates and links to state election information at its “election and voting information page” (https://www.fec.gov/introduction-campaign-finance/election-results-and-voting-information/).
How Can Voters Find Their Election Information?
The first step is identifying the congressional district and state in which a voter is registered. District boundaries and election rules can change, so older information may not reflect the current arrangement.
The U.S. House of Representatives offers an official “Find Your Representative tool” (https://www.house.gov/representatives/find-your-representative) that matches a ZIP code to a congressional district and provides links to the member’s official website.
For registration deadlines, polling locations, identification requirements, early voting, absentee ballots, and election-day procedures, voters should consult their state or local election office.
A candidate’s campaign website can explain the candidate’s positions, but the official election authority is the better source for voting instructions and deadlines.
What Should Voters Know Before Election Day?
A few practical steps can help voters prepare:
- Check voter registration status and applicable deadlines.
- Confirm the correct congressional district and the offices appearing on the ballot.
- Review official instructions for mail ballots, early voting, or in-person voting.
- Compare candidates’ stated positions with their public records and other reliable evidence.
- Verify election-related claims with official sources rather than relying exclusively on viral posts or campaign advertisements.
Election information can change as legal disputes, administrative decisions, or state-level updates occur. Voters should therefore check official sources close to the election rather than assuming that information from a previous cycle remains current.
The Bottom Line
U.S. midterm elections are congressional elections held halfway through a president’s term. All voting seats in the House are scheduled for election, while approximately one-third of Senate seats are normally contested.
The results can affect congressional leadership, legislative priorities, oversight, and federal spending decisions. The specific impact depends on the election results and the political and procedural circumstances that follow.
