Do you think Idaho should keep electing the same Republican incumbents to Congress?

Idaho voters will choose their U.S. representatives on November 3, 2026. Both of the state's two congressional districts are held by Republicans, and Reps. Russ Fulcher and Mike Simpson are running for reelection.

Why it matters

The races determine Idaho's representation in the U.S. House for the coming term. Fulcher faces two challengers in the 1st District, while Simpson seeks a 15th term in the 2nd District.

Idaho's two congressional districts are both held by Republicans, with Fulcher a four-term incumbent facing two challengers. Simpson, first elected in 1998, is seeking a 15th term in the 2nd District, where Democrat Elinor Gilbreath is the challenger.
