As of May 6, 2013, Idaho reports these voter registration figures: Republican 239,002; Democratic 55,254; independent or miscellaneous 439,715; Libertarian 3,156; Constitution 1,500.
Voter registration by party is new in Idaho. It only started in 2012. The tally last year showed far fewer members of parties, since the procedure was new and party totals essentially started from zero. The 2012 figures, for example, only showed 362 Libertarians and 225 Constitution Party members.
