Mitt: There's 'no whining in politics'

Mitt Romney is going the full "A League of Their Own" as he leaves the door open for his campaign to run negative ads against Newt Gingrich, something the former House speaker has pledged not to do (and which the pro-Romney super PAC "Restore Our Future" is doing in heavy rotation in Iowa).

"We aren't running any negative ads at this point, but we may," Romney said, per POLITICO's Reid Epstein. "This is politics. There's no whining in politics. ... You fight hard and describe the differences between yourself and other candidates."
