(CNN) - President Obama's approval rating in Florida is on the rise, according to a new poll.
A Quinnipiac University survey released Monday indicates that 50 percent of Florida voters approve of the job that Obama is doing in the White House, up five points from January, with 45 percent saying they disapprove, down four points from the beginning of the year.
The increase might have been caused by a four percent uptick in Obama's approval rating among independent voters since January. Forty-eight percent of independents now give the president a thumb's up, with 46 percent saying they disapprove, the poll shows.
Obama's recent call for increased offshore oil drilling appears to be popular with Floridians: 64 percent say they're OK with drilling off the Florida coast.
But, according to the poll, health care reform is not nearly as popular, with 48 percent saying they disapprove of the plan and 44 percent saying they support it. Forty-nine percent say they disapprove of how the president has handled health care, and 44 percent say they approve.
The survey indicates that 54 percent of Floridians disapproved of state Attorney General Bill McCollum's decision to join with other states to sue in a bid to block the new health care law; four in ten approve of his move.
McCollum, a Republican, is running for governor this year. Thirty-eight percent say McCollum's move to sue makes them less likely to vote for him for governor, with 28 percent saying it makes them more likely and three in ten saying it makes no difference.
According to the poll, McCollum leads Florida Chief Financial Officer Alex Sink, the Democratic gubernatorial candidate, 40 to 36 in a November showdown. The advantage is within the survey's sampling error. Sink faces no primary opposition. The survey indicates that McCollum leads state Sen. Paula Dockery by 49 points in the GOP primary.
"Attorney General Bill McCollum clings to a slim lead over CFO Alex Sink in the governor's race, a lead he has held since last August. He is better known than she and voters grade him somewhat better for the job he is doing. While most would rather be in his shoes, on the up side of a close race, November is a long way off," says Peter Brown, assistant director of the Quinnipiac University Polling Institute.
The Quinnipiac University poll was conducted April 8-13, with 1,250 Florida voters questioned by telephone. The survey's overall sampling error is plus or minus 2.8 percentage points.
