parties to defend.

Here are the announced House retirements that will result in open-seat elections in 2026, sorted on PVI (Cook Partisan Voting Index) based on the 2024 districts.
When a retirement occurs early in the cycle, it will be filled in a special election and not be an open-seat election in 2026.
Any seat between R+5 and D+5 is a swing district that has to be fought over,
even more so if occupied by the "wrong" party.
| Byron Donalds |
Republican |
FL-19 |
R+13 |
He is running for governor of Florida |
| Andy Biggs |
Republican |
AZ-11 |
R+11 |
He is running for governor of Arizona |
