The question

Idaho: will Other lose this seat to Republican?

Editorial read

Idaho, a mixed riding in ID, has no direct baseline for the current cycle. The Vote-Scope model projects the Republicans ahead at 58% vote share, against 33% for the Democrats, and the probability of a close race is negligible.
