Within GOP circles, Proposition 1 has turned adversaries into allies.

Right now, Idaho’s Republican primary system is closed, meaning voters must register with the state Republican Party in order to cast a vote in any of the party’s primary elections. Democratic and Republican primaries each get their own ballot under the state’s current election system.
