The re-election effort of Sen. Bill Nelson, D-Fla., has also taken a hit over the past two-and-a-half months. In late May, 48 percent of voters said he deserved re-election, but that number stands at 45 percent and 44 percent in the pre- and post-debt deal surveys, respectively. The percentage of voters who said he doesn't deserve to be re-elected rose from 30 percent in late May to 38 percent following the debt agreement. The poll did not test Nelson against any of the possible Republican candidates, but it did find that, among Republicans, there is no clear front-runner. Retired Army Col. Mike McCalister leads the pack with 15 percent of the vote. Former Sen. George LeMieux, R-Fla., is second at 12 percent, former Ruth's Chris Steak House CEO Craig Miller is third at 8 percent, and former state House Majority Leader Adam Hasner is at 6 percent. The pre-debt agreement poll was conducted July 27-31, surveying 674 registered voters, for a margin of error of +/- 3.8 percent. Interviews for the second survey began Monday, when the House approved the bill and concluded Tuesday, after the Senate moved the legislation to the White House and Obama signed it into law. That poll surveyed 743 voters, for a margin of error of +/- 3.6 percent. The Republican primary matchups for president and Senate were conducted over the duration of both polls (July 27-August 2). Those results are among 510 Republicans, for a margin of error of +/- 4.3 percent.
