(CNN) - President Obama's approval ratings are sinking in a key state that helped seal his White House victory, a new survey out Thursday suggests.
According to a new Quinnipiac University poll of Florida voters, the president's approval rating now stands at 47 percent in the Sunshine State, while 48 percent of voters there disapprove of the job he is doing.
Obama's approval in that key presidential swing state is now at a new low, and down more than 10 points from a similar survey conducted in June.
The poll also suggests the president's approval rating in Florida has largely been hurt by his aggressive push for health care reform: Only 38 percent of Florida voters believe his plan will improve the nation's healthcare system while 45 percent say it will hurt it.
Obama's approval dip in Florida largely mirrors his numbers nationwide - several recent national polls have suggested his approval rating now stands at just over 50 percent, down from 60 percent in June.
Obama beat McCain by 3 percentage points in Florida last November, 51-48 percent.
The Quinnipiac poll was conducted from August 12-17 and surveyed 1,136 voters. It carries a margin of error of plus or minus 2.9 percentage points.
