PPP's first post-conventions poll in Ohio finds Barack Obama with a 5 point lead over Mitt Romney, 50-45. This is the largest lead PPP has found for Obama in an Ohio poll since early May. Last month Obama led 48-45.
Both candidates have seen their images improve with Ohio voters in the wake of the conventions. Obama now breaks even in his approval rating at 48%, after being under water with 46% of voters approving and 51% disapproving of him a month ago. Romney's numbers are up from a 41/52 favorability rating a month ago as well, but he still remains unpopular. Only 44% see him favorably to 49% with a negative opinion.
Romney actually leads 46-44 with independents but Obama has the overall advantage thanks to a more unified party base. He leads 86/11 with Democrats, compared to Romney's 83/13 advantage with Republicans. Obama's 75 point lead within his own party is up from 70 points a month ago, suggesting that his party has coalesced around him a little bit more in the wake of a successful convention. By a 47/35 margin Ohio voters say they think the Democrats had a better convention than the Republicans.
Obama's leading in Ohio because he's not as weak there with some large voter blocs as he is in other states. He trails only 48-46 with men and 50-46 with whites, and actually leads 49-47 with seniors. His performance with those groups is far better than it is nationally- Romney would need much wider leads with them if he was going to take Ohio.
