🏠 U.S. House of Representatives — All States
Every state will have House elections on November 3, 2026. The number of seats per state is based on the most recent apportionment, and every district in every state will be on the ballot.
Example: Washington State
- All 10 U.S. House seats in Washington are up for election.
Similarly, every other state — from Alabama (7 seats) to California (52 seats) and New York (number varies) — will elect their representatives in this cycle.
🗳️ Special Elections & Odd-Year Contests
In addition to the regular cycle:
- Special Seats may be on the ballot due to vacancies (e.g., in New Jersey’s 11th District or Georgia’s 14th District earlier in 2026).
- Some states have runoff dates if no candidate achieves a majority.
🔎 What to Watch
✔ Balance of Power — Republicans currently hold the Senate majority, and all House seats are competitive in terms of potential party control shifts.
✔ Redistricting impacts — Legal battles over maps in states like Virginia and Maryland underscore how district lines shape outcomes.
✔ Primary battles — Important competitive primaries will determine the key matchups leading into November.
