Some bad political news for POTUS from that big, crucial swing state he carried in November: A Quinnipiac University Poll of Ohio voters out today shows some real slippage -  his approval ratings are now below 50 percent there - apparently driven by dissatisfaction about the economy.

Ohio voters now give President Obama a 49 percent approval rating (44 percent saying they disapprove of how he's handling his job as president). Just 46 percent approve (and 48 disapprove) of how he's handling the economy. These are significant drops in how he's viewed statewide since Quinnipiac's last survey there about two months ago. Two-thirds of Ohio voters are somewhat or very dissatisfied with how things are going in their state.

Nationally, the president still enjoys strong approval ratings, in the high-50s to mid-60s, depending on the poll. But Peter A. Brown, assistant director of the Quinnipiac University Polling Institute, said in Ohio, voters have begun to shift responsibility for the nation's woes from former President Bush to President Obama. Brown said it's a sign to Obama that "his honeymoon with the voters may be ending."

The latest Quinnipiac findings come from a survey of 1,259 Ohio voters, with a margin of error of plus or minus 2.8 percentage points.
