Idaho has 32 delegates to the Republican national convention, of which 3 are RNC and 29 are AL.[clarification needed] 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. 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.
Despite a complete lack of formal polling in the state, there were a total of four straw polls conducted in Idaho, three of which were online. Ron Paul won three of these, while Mitt Romney won another by a smaller margin.
That these totals reflect the final caucus ballots in each county; where only two candidates have votes totaled, this was likely from other candidates being eliminated in previous rounds of voting. Where all candidates have at least one vote, only one ballot was necessary, since the winning candidate had a majority of votes in that county.
Vote totals for Buddy Roemer, who had formally withdrawn from the Republican race before the caucus, are not provided.
