Former Pennsylvania Sen. Rick Santorum won the Jasper County Republican caucus by a sizable margin Tuesday evening, pacing the field with 35 percent of the vote after all the ballots finally were tallied. Ron Paul and Mitt Romney trailed with roughly 18 percent of the vote each.

With all 21 Jasper County precincts reporting, Santorum bested his competitors with 576 votes, followed by Paul with 300 and Romney with 285. Newt Gingrich was fourth with 171.

Statewide caucus results in Iowa showed a much closer race with Romney managing a narrow eight-vote victory over Santorum and Paul finishing third.
