-PPP's newest Florida Senate poll finds Bill Nelson continuing to expand his lead. He's at 46% to 37% for Connie Mack IV. Three weeks ago Nelson led by 7 points and in early July he had been ahead by only 2.
Nelson's still not popular. Only 34% of voters approve of him to 41% who disapprove. But he lucked out with an extremely weak opponent. Only 30% of voters have a favorable opinion of Mack to 44% with a negative one. Mack's numbers are a particularly dreadful 22/53 spread with independents, and he trails Nelson by 22 points with them at 48-26.
The most striking finding in the poll is that Nelson leads Mack 44-41 with white voters. If a Democrat can win white voters in Florida they're headed for a blowout victory overall, and increasingly that appears to be the case in this race
-Mitt Romney didn't get much of a bounce out of the Republican convention in Florida, but Marco Rubio sure has. His approval breakdown this month is 52/32, the best we've found for him since he took office. He's on solid 50/33 ground with independents and has a higher than normal 26% of Democrats who approve of him. Rubio's approval numbers were pretty middling for the last year and a half but he's seen a noticeable improvement since the convention.
-38% of Florida voters approve of Rick Scott this month to 48% who disapprove. His numbers, although still bad, continue to be better than they've been for most of his term. Scott trails a generic Democratic opponent for reelection by a 48/42 margin.
