The results from Iowa suggest what has been clear for months: Republicans remain divided about their presidential choices.
Former Massachusetts Gov. Mitt Romney eked out an eight-vote win after he and former Pennsylvania Sen. Rick Santorum swapped the slimmest of leads back and forth in Tuesday's caucuses. With returns complete, each had won the support of roughly 25 percent of caucusgoers.
Despite the near-tie, Iowa caucus rules do not allow for a recount. Texas Rep. Ron Paul was third at 21.5 percent, according to The Associated Press.
