President Obama and Mitt Romney are running neck-and-neck in vote-rich Florida, according to a new Mason-Dixon poll released on Saturday.

Obama leads Romney in the poll, 46 percent to 45 percent, well within the poll’s margin of error. Two percent of likely voters say they would vote for former New Mexico Gov. Gary Johnson, who initially sought the Republican nomination but now intends to run as an independent. Seven percent are undecided. The poll was conducted for the Miami Herald, Tampa Bay Times, the Spanish-language El Nuevo Herald and two in-state cable news stations.

Each candidate wins more than 80 percent of voters in his own party, the poll shows. The two are virtually tied among independents, with Obama holding a statistically insignificant 5-point lead.
