Sen. Bill Nelson, D-Fla., is a significant favorite to win re-election, according to a new NBC News/Wall Street Journal/Marist poll. While the presidential race in the state is a toss-up, Nelson maintains a double-digit advantage in his bid for a third term.
Nelson leads GOP Rep. Connie Mack, 52 percent to 39 percent, with 9 percent undecided. In the previous poll, conducted Sept. 30 through Oct. 1, the Democrat had a 52 percent to 41 percent advantage.
Mack significantly underperforms Mitt Romney, who garners 47 percent support in the poll. Romney trails President Obama by one percentage point, but the president's lead is within the poll's margin of error.
Mack has tied himself to Romney throughout the campaign, but 15 percent of respondents who support Romney in the presidential race choose Nelson over the Republican in the Senate contest. Mack attracts just 5 percent of Obama voters. Nelson also has a big advantage among self-identified independents, leading Mack 51 percent to 35 percent.
The survey of 988 likely voters was conducted Oct. 7 through Oct. 9. The poll's margin of error is plus-or-minus 3.1 percentage points.
