President Obama returns to majority approval in the state, as 53% now approve of the job he's doing; last month he was down to 49%. The president is also more trusted to handle health care than congressional Republicans by a 49%-28% margin.

"Perhaps it's because the poll was taken immediately after the President's nationally-televised prime-time speech to Congress, but Democratic fortunes in Ohio have improved slightly across-the- board," said Peter Brown, assistant director of the Quinnipiac University Polling Institute. "Not only have the President's numbers improved, but so have those of Gov. Ted Strickland and the party's two U.S. Senate candidates."
