Romney pushes back: If I'm weak, what's Gingrich?

By Catalina Camia, USA TODAY

Mitt Romney had a snappy rejoinder this morning to Newt Gingrich's comment that he is a weak GOP front-runner.

"If I'm a weak front-runner, what does that make Newt Gingrich because I'm well ahead of him, " Romney said on Fox News. "I'm happy to be solidly ahead."

Romney has racked up a string of popular vote victories in key states and has 454 delegates as of this morning, compared with two state wins for Gingrich (South Carolina and Georgia) and 107 delegates.

Gingrich called Romney "not a very strong front-runner" during an interview Sunday on Fox News.

Romney said this morning that he believes he'll become the GOP presidential nominee and denounced Gingrich and Rick Santorum for their long Washington careers.
