(CNN) – A second straight poll in Florida shows Democrat Alex Sink faltering in her gubernatorial bid.
The survey from Quinnipiac University shows Republican Rick Scott, the controversial former health care CEO, with a 49 to 43 percent advantage over Sink, the state's chief financial officer.
But the two candidates have nearly identical favorability ratings, suggesting Sink may be most hindered by her Democratic affiliation in what appears to be a Republican year.
The same poll finds President Obama with only a 40 percent approval rating and a 56 percent disapproval.
A recent CNN/Time Magazine poll survey showed Sink down two points - among the first surveys to show the Democratic candidate losing ground in the key gubernatorial race.
The Quinnipiac poll surveyed 1,151 likely voters by telephone from September 23-28, and carries a sampling error of plus or minus three percentage points.
