Sen. Bill Nelson (D-FL) holds a 5-point lead in his increasingly tight bid for a third term, according to a new poll released Friday.
In the latest new Mason-Dixon poll, Nelson earns the support of 47 percent of Florida voters, while Rep. Connie Mack (R-FL), who is widely expected to claim his party's nomination in the Aug. 14 primary, trails with 42 percent.
The PollTracker Average currently shows the race as a tossup. Mason-Dixon conducted its poll July 9-11 using live telephone interviews with 800 registered Florida voters. It has a margin of error of 3.5 percent.
