FILE - In this Jan. 26, 2012 file photo, Republican presidential candidates, former House Speaker Newt Gingrich and former Massachusetts Gov. Mitt Romney talk during a commercial break at the Republican presidential candidates debate in Jacksonville, Fla. Remember Gingrich calling Romney a liar? Michele Bachmann saying Romney's unelectable? Rick Santorum calling Romney "the worst Republican in the country" to run against Obama? They're hoping you don't. And acting like it never happened _ even though most of their words are just clicks away online. (AP Photo/Matt Rourke, File)
