(CNN) - A new poll suggests that Barack Obama's approval rating is dropping rapidly in Ohio, a crucial battleground in the race for the White House, and a state with a U.S. Senate seat and governorship up for grabs next year.
Forty-nine percent of those questioned in a Quinnpiac University survey released Tuesday say they approve of how Obama's handling his duties as president. That's down 13 points from a Quinnipiac University poll of Ohio voters conducted in May. Forty-four percent of those questioned disapprove of Obama's job as president, up 13 points from May.
The survey also indicates that by a narrow 48 percent to 46 percent margin - within the range of the survey's 2.8 percent sampling error - Ohio voters disapprove of how Obama's handing the economy. In May, 57 percent approved of how Obama was handling the economy.
"The economy in Ohio is as bad as anywhere in America. These numbers indicate that for the first time voters have decided that President Barack Obama bears sole responsibility for their problems," says Peter A. Brown, assistant director of the Quinnipiac University Polling Institute.
According to the survey, 85 percent of Democrats give the President an overall thumbs-up, but only 38 percent of independents and 19 percent of Republicans approve of the job Obama's doing as president.
Ohio was the state that put George W. Bush over the top in his 2004 re-election. Last year, Obama carried the state by 5 points over Sen. John McCain.
The Quinnipiac University telephone poll of 1,259 voters was conducted June 26-July 1.
