Former Massachusetts Governor Mitt Romney edged out former Senator Rick Santorum by just eight votes in Tuesday night's Iowa caucuses. After spending most of the night locked in a dead heat with Santorum and Rep. Ron Paul, Romney was declared the winner early Wednesday morning with 24.6 percent of the vote. Paul finished in third place, followed by Newt Gingrich, Rick Perry, and Michele Bachmann. Perry announced he would suspend his campaign to return to Texas.
