But since Florida -- when Giuliani's third-place showing caused him to drop out and Huckabee placed a distant fourth -- Romney's campaign has worked hard to portray the GOP race as a two-man contest. Activists such as Hannity and former senator Rick Santorum (Pa.) are organizing a stop-McCain movement with Romney as their standard-bearer.
"If you're a Republican, if you're a Republican in the broadest sense, there is only one place to go right now and that's Mitt Romney," Santorum said on a radio show hosted by Laura Ingraham, another Romney backer.
