Former Mass. Gov. Mitt Romney has opened up a 20-point lead in the final days leading up to the Republican primary in Florida, according to a Suffolk University/7NEWS (WSVN-Miami) poll of likely Republican primary voters in Florida.  

Romney led Newt Gingrich 47 percent to 27 percent, while Rick Santorum got 12 percent and Ron Paul finished fourth with 9 percent, according to today's poll. 

Five percent were undecided.  

 “It is almost certain that Mitt Romney will top his 39 percent showing in New Hampshire,” said David Paleologos, director of the Suffolk University Political Research Center in Boston. “This poll also tells us that Romney could reverse and exceed Newt Gingrich’s percentage and margin in South Carolina – and do it in Gingrich’s backyard.”  

Romney led Gingrich 55 percent to 24 percent among those voters who indicated that they had already voted, and he led 56 percent to 23 percent among Hispanic voters.   "If Mitt Romney hits a historic benchmark in this election, he has Hispanic voters to thank,” said Paleologos.
