Kootenai County still hasn't reported yet. According to the CDA Press, Santorum won the first round of balloting there with 35%, but no word on the final tally yet.
Romney came in third; the runoff was between Santorum and Paul.
Counties where Romney came in third:
Benewah
Kootenai
Idaho
Clearwater
Bonner
Boundary
Romney came in second in Shoshone because there are so few active Republicans there (Democrats regularly turnout 2 to 3 times more voters during primaries). The only people who voted for him there were Mormons.
