Romney, Gingrich stole debate spotlight

The four leading Republican presidential candidates took the stage last night in the last debate before the Florida primaries. It was a rivalry between Mitt Romney and Newt Gingrich, however, that stole the show.

Romney blunted Gingrich's attacks on immigration and his personal investments in Goldman Sachs, Fannie Mae and Freddie Mac.

"Maybe Gov. Romney, in the spirit of openness, should tell us how much money he's made off of how many households that have been foreclosed by his investments," snapped Gingrich.

Romney fired back with questions about Gingrich's similar investment activities. "Have you checked your own investments? You also have investments through mutual funds that also invest in Fannie Mae and Freddie Mac."

It's been a rough couple of days for Gingrich. After the former house speaker won South Carolina, polls show him slipping precipitously in Florida. On top of that, the GOP establishment is going after him. Former Senate majority leader Bob Dole said when Gingrich was speaker, he "had a new idea every minute, and most of them off-the-wall."

When asked who won the debate, Gingrich's own spokesman said "it was a push."

As for President Obama, he told Diane Sawyer he's not watching his potential rivals trade punches.

“Whoever wins the Republican nomination is going to be a standard bearer for a vision of the country that I don't think reflects who we are,” he said.
