PPP continues to find Barack Obama as the favorite in Iowa, although the race in the state is a good deal closer than it was in both 2008 and on our last poll in early May. Obama leads by 5 points, 48-43, after previously holding a 10 point advantage at 51-41.
Iowa voters have flipped from narrow approval of Obama (49/46) to narrow disapproval of him (47/49) over the last couple months. His numbers are pretty steady with Democrats and Republicans but with independents he's gone from 52/41 to 45/48. Fortunately for Obama, Romney's not very popular either. Only 37% of voters have a favorable opinion of him to 55% with a negative one. That -18 spread is up a bit from its -22 standing at 34/56 the last time PPP polled Iowa, but it's still indicative of an electorate that's not exactly warming up to him yet.
Iowa really exemplifies how critical women are to Obama's reelection hopes. He leads 54-37 with them, helping to offset a 48-43 disadvantage with men. Iowa's also a state where Obama continues to benefit from a party unity gap, taking 87% of Democrats to Romney's 84% of Republicans. If Romney can close that up the state will tighten further. Obama leads 46-38 with independents, although that's down a good deal from his 54-34 lead in May.
Iowa voters have been closely divided on Terry Branstad ever since his return to office and that's no different on this poll- 45% approve of him to 43% disapprove. On the off chance he was Romney's running mate, Obama would lead their ticket 49-42. On the even offer chance Romney made a play to conservatives by picking Steve King Obama's lead would rise to 48/40. King is not very popular statewide, with a 26/37 favorability rating.
Iowa and Wisconsin are in a very similar boat right now- Obama's not nearly as strong in either as he was in 2008, but he does still look like a clear favorite at least for the time being.
