2012 Idaho Republican presidential caucuses

The Republican caucuses took place on Super Tuesday, March 6, 2012. An advisory primary with no binding effect on delegates, scheduled to be held on Tuesday May 15, 2012, was cancelled by the Idaho Republican Party. Five candidates were on the ballot. In order of filing they are Ron Paul, Mitt Romney, Rick Santorum, Newt Gingrich, and Buddy Roemer. Although Roemer had withdrawn from the Republican race before the Idaho caucus, he still appeared on the ballot.

Mitt Romney won 61% of the vote, thanks to a large majority of support (80-90% in most counties) in majority Mormon southeastern Idaho, rendering it a winner-take-all contest. Santorum and Paul split the Panhandle, winning five counties each, but came away empty in the delegate count.

Procedure
Idaho has 32 delegates to the Republican national convention, of which 3 are RNC and 29 are AL. The 3 RNC delegates pledged to go with the results of the Boise Straw Poll. The delegates will be determined by the caucuses results, based on a two-step approach. First, the delegates are primarily awarded winner-take-all by county after a series of votes in which candidates are successively removed from the ballot. Then, if a candidate receives half or more of the county delegates, he will receive all the 32 delegates; if not, the delegates will be split proportionately according to the number of county delegates.

Straw polls
Despite a complete lack of formal polling in the state, there were a total of five straw polls conducted in Idaho, three of which were online. Ron Paul won three of these,  while Mitt Romney won two.
