35 Senate seats face voters in 2026 — 22 Republican-held, 13 Democratic-held. That is the 33 Class 2 seats plus two appointee specials, derived from each member's term end date rather than a hand-kept list. Every one of these members is open to the public below.
All 435 House seats are on the ballot too, as they are every two years. That is why only Senate cards carry a ballot badge: a mark every card wears is not a mark.
Split delegations. 4 states are represented by senators of different parties. Only one of those seats is on the 2026 ballot: Susan M. Collins (ME). That is a fact about who holds the seats today, not a prediction about who will.
4 of these are rated a toss-up and 5 more are rated competitive, by Decision Desk HQ and Sabato's Crystal Ball. Those ratings are theirs, not ours — every one carries its source and the date it was made, and none of them touches a grade. A grade comes only from roll calls we verified against the official record. The unrated seats below are not safe seats; they are seats nobody we cite has rated.
