On March 17, two bills were introduced in the Idaho Senate to revise the primary system. Idaho now uses an Open Primary, in which each voter on primary day decides in the secrecy of the voting booth which party primary to vote in.

S. 1506 would provide for registration by party, and also would legalize nominating conventions for parties that would rather use conventions than primaries (Idaho already has conventions for new parties).

S. 1507 would authorize closed primaries. Neither bill has made any headway as of March 25.
