Sen. Bill Nelson (D-Fla.) can't top 50 percent against several potential Republican opponents, according to a new Mason-Dixon poll released Tuesday morning; the latest sign he may be vulnerable to a Republican challenger in 2012.
According to the results of the poll, which was commissioned by Ron Sachs Communications, in hypothetical head to head matchups, Nelson leads Rep. Connie Mack 45 percent to 40 percent, former Sen. George LeMieux 49 percent to 35 percent, state Senate Pres. Mike Haridopolos 48 percent to 25 percent, and former state Rep. Adam Hasner 46 percent to 24 percent.
Mack, LeMieux and Hasner are considering Senate runs while Haridopolos announced his bid in January. Outside of Mack, whose father served in the Senate, none of the Republicans have much name identification with the public.
The poll of 625 registered Florida voters was conducted Feb. 9-10, and has a margin of error of plus or minus 4 percent. 274 Democrats, 248 Republicans and 103 independent/other voters were surveyed.
The one Republican in the poll who leads Nelson? Former Gov. Jeb Bush, who tops Nelson 49 percent to 41 percent. But Bush has said he will not run against Nelson in 2012.
