It was a foregone conclusion given the fact that there are so many Mormons there:

Mormons almost unanimously supported Mitt Romney in his easy victory Saturday in Nevada’s Republican presidential caucuses, a preliminary survey found.
Mormons comprised a quarter of those attending Nevada’s GOP caucuses, and more than nine in 10 were voting for Romney, according to early results from the survey conducted for The Associated Press and television networks. Romney is a Mormon, and his religion has been cited as a problem by some Republican voters.
A narrow majority of those identifying themselves as Republicans—the bulk of the voters—backed Romney. Two-thirds of independents favored Ron Paul but they made up only about 10 percent of GOP caucusgoers. Romney and Paul were the only Republican candidates to campaign much in Nevada
