PPP's first Wisconsin poll since Mitt Romney announced Paul Ryan as his running mate finds him taking a small lead over Barack Obama in the state, 48-47. That represents a 7 point shift from PPP's last look at the state in early July, which found Obama ahead 50-44.
Particularly interesting is how this breaks down:
The biggest change Ryan's selection seems to have brought about is the unification of the GOP. Romney's gone from a 78 point lead with Republicans on our last poll (87-9) to now an 88 point lead with them (93-5). There's also been a tightening with independents. Obama still has a 4 point lead with them at 47-43, but that's down from a 14 point advantage at 53-39 six weeks ago. Democrats are unchanged from the previous poll.
I've been skeptical from the get-go (though hoping to be proved wrong) that we'd be able to flip Wisconsin this time around, as I thought that the extrapolations from the Walker recall got excessively enthusiastic. And while this news is encouraging, being within the margin of error is still far from a slam dunk (and, as noted in the comments, PPP is far from the last word on such matters).
That being said, you have to be heartened by the direction the Badger State is moving in, particularly as revelations of the Obama campaign's financial difficulties come to the surface. If the Romney campaign can effectively expand the map of battleground states at the same time that Obama's fundraising efforts flag, the White House gets caught in a vicious cycle that it's difficult to claw out of. That could be a lot of fun to watch.
