2026 midterm elections explained
The 2026 midterms are the congressional and state elections held halfway through a president's four-year term. They are not a single election. They are thousands of separate contests run under state law, and the results decide who writes federal law for the second half of the term.
Three numbers frame the whole night:
- 435 House seats, all up every two years.
- 35 Senate seats, including special elections in Florida and Ohio.
- 36 governorships, plus territorial races we do not cover here.
The rest is arithmetic. Republicans hold 218 House seats, Democrats 214, with one independent caucusing with Republicans and two vacancies. Democrats need a net gain of about three seats to take the House. In the Senate, Republicans hold 53 seats and Democrats 47; Democrats need a net gain of four to reach 51, because a 50–50 chamber is controlled by the Republican caucus and the vice president breaks ties.
Why the midterms matter
A midterm is a referendum on the party in power, and it usually goes badly for that party. Republicans won the White House and both chambers in 2024, so 2026 is the first national test of how voters judge that record.
The stakes go beyond the scoreboard:
- The House writes the spending bills. Control decides what reaches a floor vote on taxes, health programs, and the debt limit.
- The Senate confirms judges. A one-seat swing changes who sits on federal courts for decades.
- Governors run elections. In most states, the governor and secretary of state shape how ballots are administered in 2028.
Pew Research Center's September 28–October 4, 2026 survey found that 84 percent of voters call the economy very important to their vote, followed by the future of democracy at 73 percent and health care at 68 percent. Our issues hub tracks those debates.
The four questions we answer
What are midterm elections?
A midterm is the general election held in the middle of a presidential term. It includes all 435 House seats, about a third of the Senate, and most governorships. Turnout is usually lower than in a presidential year, which makes the composition of the electorate as important as the national mood. Read What Are Midterm Elections? for the full explainer.
Why do midterms matter?
Because they decide who controls Congress for the last two years of a presidency, and because the party that wins governorships and state legislatures draws the maps that shape the next decade. Read Why Do Midterms Matter? for the long version.
What is the balance of power right now?
Republicans control the House 218–214, with one independent caucusing with them and two vacancies, and the Senate 53–47. The balance of power explainer walks through the seat math, the vacancies, and what a 50–50 Senate would mean. The Senate hub, House hub, and governors hub track the individual races.
Who could be speaker in 2027?
The speaker is chosen by the House majority after the election, not by voters directly. If control flips, the next speaker could come from a leadership fight that starts the week after November 3. Read Who Could Be Speaker in 2027? for the process and the names in contention.

Registration and mail-ballot deadlines come first, and they have already passed in several states. The voting hub links every state guide we publish.
How to read our race pages
Each race hub follows the same structure: the matchup, the seat's significance, the money, the polling (linked to outside trackers rather than copied numbers), the voting rules, and the results. We name the rater and the date whenever we cite a race rating, because Cook Political Report, Sabato's Crystal Ball, and Decision Desk HQ do not use the same scale.
The results hub is the place to start on election night. It explains when polls close, which outlets call races, and why a call is not a certification.
Frequently Asked Questions
When are the 2026 midterm elections?
Tuesday, November 3, 2026. Early voting and mail balloting are already under way in many states, and deadlines vary by state.
How many seats are up in 2026?
All 435 House seats, 35 Senate seats, and 36 governorships. The Senate total includes regular elections and special elections in Florida and Ohio.
Do midterms usually favor the president's party?
No. Midterms usually cost the president's party seats, which is why control of Congress is competitive even though Republicans won the 2024 elections.
What do Democrats need to win the House?
A net gain of about three seats, given the current 218–214 line with one independent caucusing with Republicans and two vacancies. Vacancies and redistricting can move that number.
What do Democrats need to win the Senate?
A net gain of four seats to reach 51. A 50–50 Senate would be controlled by Republicans because the vice president breaks ties.
