Voters debate during a caucus of precinct 42 near Smithland, Iowa, Tuesday, Jan. 3, 2012. Former Massachusetts Gov. Mitt Romney, Texas Rep. Ron Paul and former Pennsylvania Sen. Rick Santorum shared the straw poll ballot with former House Speaker Newt Gingrich, Texas Gov. Rick Perry and Minnesota Rep. Michele Bachmann in a caucus race as jumbled as any in the 40 years since Iowa gained the presidential campaign lead-off position. (AP Photo/Dave Weaver)
