Every two years, Americans head to the polls to choose who represents them in Congress, and the elections that fall halfway through a presidential term are known as the midterms. The 2026 midterm elections take place on Tuesday, November 3, 2026, and they will decide every seat in the U.S. House of Representatives, about a third of the Senate, dozens of governorships and thousands of state and local offices.

10 Essential Facts About the 2026 Midterm Elections
1. Why They Are Called Midterms
Presidents serve four-year terms, while members of the House serve two-year terms. Contests such as the 2026 midterm elections, held in the middle of a presidential term, when the presidency itself is not on the ballot, are called midterm elections. The 2026 midterm elections fall halfway through the presidential term that began in January 2025.
2. Every House Seat Is on the Ballot
The House of Representatives has 435 voting members, with seats divided among the states by population based on the census. Every one of those seats is up for election every two years, including in the 2026 midterm elections. Voters in the District of Columbia and several U.S. territories also elect non-voting delegates.
3. About One-Third of the Senate Is Up
The Senate has 100 members, two from each state, serving staggered six-year terms. That means roughly one-third of seats are elected every two years. In 2026, 33 seats are regularly scheduled, and special elections are also held to fill the remainder of terms where a senator left office early, such as in Ohio and Florida.
4. Thirty-Six Governors Are Elected
Many states elect governors in midterm years, which makes the 2026 midterm elections especially busy at the state level. In 2026, 36 states hold races for governor, along with other statewide offices such as attorney general and secretary of state in many places.
5. State Legislatures and Local Offices Matter Too
Most states hold elections for state legislative seats, and ballots often include county officials, judges, school boards and mayors. These officials make decisions about schools, roads, public safety and local taxes, so down-ballot races can affect daily life directly.
6. Ballot Measures Let Voters Decide Directly
In many states, citizens vote directly on ballot measures, including constitutional amendments, initiatives and bond issues. Your state election office usually publishes a voter guide explaining each measure in neutral terms.
7. Control of Congress Is Decided by Majorities
A party needs at least 218 seats for a House majority. In the Senate, 51 seats is a majority, and the vice president can break a tie. The majority party in each chamber chooses leaders and committee chairs, which shapes which bills move forward.
8. Primaries Come First
Before the general election, most states hold primaries to choose each party’s nominees. Primary dates in 2026 are spread across the year and vary by state. Some states also hold runoff elections if no candidate wins a required majority.
9. Rules Are Set by States
Federal law sets some standards, but each state runs its own elections. That means registration deadlines, early voting, mail voting and ID rules differ depending on where you live.
10. Results Take Time to Certify
After polls close in the 2026 midterm elections, media outlets may project winners on election night, but official results are counted and certified by state and local officials over the following days and weeks. Close races can take longer, especially when many mail ballots are counted after Election Day.

How Congress Works
The House of Representatives
Under Article I of the Constitution, House members must be at least 25 years old, U.S. citizens for at least seven years, and residents of the state they represent. The House has the sole power to start revenue bills and to impeach federal officials. Its leader, the Speaker of the House, is elected by the members. Learn more at the official House website.
The Senate
Senators must be at least 30 years old, citizens for at least nine years, and residents of their state. The Senate confirms many presidential appointments, including federal judges and cabinet members, and approves treaties. It also holds trials when officials are impeached by the House.
How a Bill Becomes Law
Both chambers must pass identical versions of a bill before it goes to the president, who can sign it or veto it. Congress can override a veto with a two-thirds vote in both chambers.
How to Register and Vote in the 2026 Midterm Elections
Check Your Eligibility
To vote in federal elections, you must be a U.S. citizen, meet your state’s residency requirements, and be 18 years old by Election Day. Some states allow 17-year-olds to pre-register or vote in primaries if they will turn 18 by the general election. Rules for people with past felony convictions vary by state.
Register or Confirm Your Registration
Visit vote.gov, the official U.S. government site, to register or find your state’s registration rules. Many states offer online registration, and some allow same-day registration at the polls. North Dakota does not require voter registration. You can also use the National Mail Voter Registration Form from the U.S. Election Assistance Commission. Deadlines can be weeks before Election Day, so check early.
Choose How to Vote
- In person on Election Day: Find your polling place through your state or local election office.
- Early in-person voting: Most states offer a period of early voting before Election Day.
- By mail: Every state offers absentee or mail voting in some form, and several states send ballots to all registered voters. Follow your state’s deadlines for requesting and returning a ballot.
- Military and overseas voters: The Federal Voting Assistance Program helps service members, their families and citizens abroad.
Know What to Bring
Voter ID requirements vary. Some states ask for photo ID, others accept non-photo documents, and some require none for most voters. Check your state election office website before you go. USA.gov links to every state’s official election resources.
Preview Your Ballot
Many states and counties publish sample ballots online. Reviewing yours in advance helps you research down-ballot races and ballot measures from official, neutral sources.
Key Dates to Track for the 2026 Midterm Elections
Because states set their own calendars, the most important dates for the 2026 midterm elections depend on where you are registered. Here is a general checklist to complete with your state election office:
- Voter registration deadline: Often between 15 and 30 days before Election Day, though some states allow registration up to and including Election Day.
- Mail ballot request deadline: If your state requires an application, there is a final date to request a ballot.
- Early voting period: Start and end dates, plus locations and hours, vary by county.
- Mail ballot return deadline: Some states require ballots to arrive by Election Day; others accept ballots postmarked by Election Day that arrive within a set window.
- Election Day: November 3, 2026. Polling hours are set by each state.
- Possible runoffs: A few states hold runoffs after November if no candidate wins a required majority.
Write these dates down or add them to your phone calendar as soon as your state publishes them. Missing a deadline is one of the most common reasons eligible voters are unable to cast a ballot in the 2026 midterm elections.
Campaign Finance and the FEC
The Federal Election Commission is the independent agency that enforces federal campaign finance law. It does not run elections, but it collects and publishes reports on how federal candidates, parties and political committees raise and spend money. Anyone can search those filings on the FEC website to see contributions and spending for House and Senate campaigns in the 2026 midterm elections.
Tips for Informed Voting
- Use official sources. Get dates, deadlines and polling locations from your state or local election office.
- Be wary of misinformation. Our guide on how to spot fake news can help you evaluate what you see online.
- Make a plan. Decide when, where and how you will vote, and put deadlines in your calendar.
- Consider volunteering. Many counties need poll workers; your local election office can tell you how to sign up.
