[Newsmax] There is growing talk that if former House Speaker Newt Gingrich drops out of the race and "suspends" his campaign, he may throw his support behind Rick Santorum in an effort to deny Mitt Romney the GOP nomination.

And, for the moment, Gingrich is not yielding to the slew of establishment endorsements for Mitt Romney.

Gingrich told CBS News' "Face the Nation" Sunday that Romney has no lock on the nomination and the math doesn't show him getting the 1,144 delegates easily to clinch the nomination.

A leading Gingrich campaign official also suggested this weekend that their camp may work with Santorum to stop Romney from getting the nomination as the former House Speaker made clear he could back either Santorum or Romney
