A CNN/Time/ORC International Poll also indicates that while Gingrich surged following his 12-point victory in Saturday's South Carolina primary, his momentum appears to be quickly cooling off.
According to the poll, 36% of people likely to vote in Tuesday's Republican primary in the Sunshine State say they are backing Romney as the party's nominee, with 34% supporting Gingrich. The former Massachusetts governor's two point margin over the former House speaker is well within the survey's sampling error.
