It was an Iowa caucus night that came down to the wire, with former Massachusetts Gov. Mitt Romney and former Pennsylvania U.S. Sen. Rick Santorum running neck-and-neck for first place in the contest for the Republican presidential nomination. At 1:36 a.m. Wednesday, the Republican Party of Iowa declared Romney the winner by just eight votes over Santorum, the dark-horse candidate who ran his campaign on a shoestring budget.
