Idaho’s election system likely will not change, after voters largely rejected Prop 1. By midnight, 419,211 ballots statewide were reported cast against, or 69.3%, with 185,945 in favor, preliminary results show. The ballot measure, created and supported by the group Idahoans for Open Primaries, would have meant anyone regardless of party affiliation could vote in Idaho primaries in a new top-four contest. It would’ve also implemented ranked-choice voting in the general election. Supporters for the initiative conceded at about 11:30 p.m.
