"Idaho law provides for a presidential primary in May (simultaneous with the primary for other office). However, on July 16, the Republican State Central Committee voted to choose delegates to the national convention by caucus on March 6. Because the Democrats also usually choose delegates by caucus in Idaho, and because the state’s two ballot-qualified minor parties normally don’t use a presidential primary, this means the 2012 presidential primary in Idaho will be completely meaningless. Republicans will discuss with Democrats the idea of a bill early in the 2012 legisiative session to eliminate the presidential primary."
