Bill Nelson leads Rep. Connie Mack, 49 percent to 35 percent, with 12 percent undecided, according to a new poll from Fox News.
Nelson’s vote share is identical to that of President Obama, but Mack lags behind his party’s standardbearer, Mitt Romney, who captures 44 percent of the vote at the top of the ticket. An NBC News/Wall Street Journal/Marist poll last week also gave Nelson a 14-point lead.
