Will exactly 3 House Democratic members lose their primary in 2026?

To be included, candidates must: be running in an election for the office they currently hold (regardless of District), for a party they are currently in, as of primary day for the seat they're contesting in in 2026; be running for the nomination of a position whose election day is on the same date as most Congressional elections in 2026, typically an early Tuesday of November; and lose the Democratic primary for that election to another candidate.
