2026 Midterms
How U.S. Midterm Elections Work — A Complete Guide
Every two years, Americans elect all 435 members of the House of Representatives and roughly one-third of the Senate. When these elections fall in the middle of a presidential term — as in 2026 — they are called midterm elections. For international observers and first-time voters alike, the U.S. electoral system can seem complex. Here is a plain-language guide to how it works.
The structure of the U.S. Congress
The U.S. Congress has two chambers — the House and the Senate — and both must pass legislation before it can become law. Understanding midterms requires understanding how each chamber is structured.
The House of Representatives
435 members, each representing a congressional district. Terms are two years — meaning every seat is up for election every two years. Larger states have more representatives; the smallest states have just one. The House initiates all revenue bills and has the sole power to impeach federal officials including the president.
The Senate
100 members — two from each of the 50 states. Terms are six years, staggered so that roughly one-third of seats come up for election every two years. The Senate ratifies treaties, confirms presidential appointments (judges, cabinet members), and conducts impeachment trials. Conviction in the Senate requires a two-thirds supermajority.
Why midterms happen every two years
The Founders designed the House with two-year terms deliberately — to keep representatives closely accountable to their constituents. The Senate's longer terms provide stability and continuity. The result is an electoral cycle where Americans vote every two years: for president every four years, and for Congress every two years, including the midpoint of each presidential term.
What is on the ballot in 2026?
In November 2026, American voters will see several types of races on their ballots, depending on their state.
Federal races appear on every ballot: their congressional district's House seat (all 435 are contested) and, if their state's Senate seat is up, the Senate race (33 seats in 2026).
State races vary by state: 36 states hold governor elections in 2026, plus state legislative races, attorney general contests, and ballot measures on specific policy questions.
Local races vary by county and municipality: school board elections, city council seats, judges, sheriffs, and local ballot measures are commonly included.
How does the winner-take-all system work?
In most U.S. congressional elections, the candidate with the most votes wins — even without a majority. This "first past the post" system means a candidate can win with 40% of the vote if the other two candidates split the remaining 60%. A small number of states use ranked-choice voting, where voters rank candidates in order of preference.
There are no runoff elections in most states for general elections — whoever gets the most votes on Election Day wins the seat.
Why do midterms matter so much?
Control of Congress determines what legislation can pass. A president with a Congress controlled by their own party can pass ambitious legislation; a president facing an opposition Congress is effectively limited to executive actions and veto power.
Midterms also shape the next presidential election — strong midterm performances create momentum and front-runner status for 2028 candidates, while weak performances can effectively end political careers or signal a party's strategic direction.
Common questions
Can non-U.S. citizens vote in midterms?
No. Only U.S. citizens who are registered voters can vote in federal elections, including midterms. Voter registration requirements and deadlines vary by state.
Do midterm results affect Trump's presidency?
Midterms affect Trump's ability to govern but not his term length. He serves until January 20, 2029 regardless of results. However, a Democratic Congress could block legislation, increase oversight, and potentially initiate impeachment proceedings.
When do we know the midterm results?
Most results are known on election night (November 3, 2026) or within a few days. Close races in states with significant mail-in voting can take longer. Final results are certified by each state over the following weeks.
