2026 Idaho Uncontested Seats: Where November Is Already Decided
Published May 25, 2026 · Based on candidate filings from voteidaho.gov
Idaho voters will see 105 state legislative seats on the November 3, 2026 general election ballot — 35 Senate seats and 70 House seats. For 19 of them, the November contest is either already over or effectively over: 11 seats had only one party file candidates at all, and another 8 face only minor-party challengers rather than a major-party opponent.
9 Republican-only seats
In these districts, no Democratic, Libertarian, Constitution, or Independent candidate filed. The Republican primary winner (or the sole candidate, where the primary was uncontested) wins the general election by virtue of being the only name on the November ballot.

Federal and statewide: all contested
Unlike the legislative races, every 2026 Idaho federal and statewide constitutional office has both a Republican and a Democratic candidate going to November. U.S. Senator (Jim Risch vs David Roth), the two U.S. House seats, Governor (Brad Little vs Terri Pickens), and all five down-ballot constitutional offices (Lt Governor, Secretary of State, Attorney General, State Controller, State Treasurer, plus the nonpartisan Superintendent of Public Instruction) feature contested general-election ballots. Minor-party candidates filed in many of these races as well.
Why this matters
Seventeen percent of Idaho's legislative seats are effectively decided before the general election begins. Voters in those districts can still cast a ballot in the relevant primary (in May) to choose who represents them, but by November those races have no competitive choice. Cross-reference the seat counts here with the primary results coverage to see who actually heads to office in January 2027.
For District 18 voters (the two Democratic-only seats), the same is true in reverse: a single Democrat is on the ballot for both House seats and for the Senate seat. District 18 covers parts of Boise and is one of the few legislative districts in Idaho where Democrats consistently outperform Republicans in general elections.
