Only 36 percent of respondents like Nelson and 12 percent did not recognize him, an encouraging sign for Mack who has name recognition due to his father.
“Nelson is vulnerable,” said Brad Coker of Mason-Dixon Polling & Research, a nonpartisan, Jacksonville-based company that conducted the poll.
A Rasmussen poll came out Thursday that had Mack leading Nelson by a 46 to 37 percent margin.
Still, there is good news for Nelson in the latest poll. The senator holds a strong–50 to 39 percent– lead with independents. He also holds a big advantage with women, leading Mack by a 52 to 37 percent margin.
In terms of region, Nelson is strongest in Southeast Florida, leading Mack by a 53 to 33 percent. Mack, meanwhile, is strongest in Southwest Florida, leading Nelson by a 55 to 38 percent.
The telephone survey of 800 registered Florida voters was conducted July 9-11 and has a margin of error of 3.5 percentage points.
