With his impressive Florida win on Tuesday, Mitt Romney has re-established himself as the clear front-runner for the Republican presidential nomination. But he continues to face fervent opposition from some quarters, and a number of hurdles remain before he can claim the nomination.
Romney took just over 46 percent of the vote, while second-place finisher Newt Gingrich had nearly 32 percent.
Former Pennsylvania Sen. Rick Santorum had about 13 percent, with Texas Rep. Ron Paul at 7 percent.
NPR political correspondent Don Gonyea sends a photo from Newt Gingrich's Florida primary night headquarters in the big ballroom at Orlando's Rosen Centre of workers putting a big "Newt" sign into place as a backdrop for what's expected to be a tough night for the speaker. The workers may be giving the GOP presidential candidate the only "lift" he'll get all evening.
