After Obama's slanderfest of PAC-ads and baseless surrogate attacks over the last 2 months, where he had a larger war-chest to spend than Romney, Obama has only gained a point or two after the tens of millions Obama spent on negative campaigning.

It's still very tight, even after all that. I think this week will reflect a good bounce for Romney, because:

1) the vile attack ad where an Obama-PAC-ad accuses Romney of being responsible for some steel-worker's wife dying of cancer (despite that she was never insured on her husband's Bain-controlled insurance, that she always had her own insurance through her own job. And that she was insured through her job for another 5 years before beign diagnosed with cancer, and died 6 years after her husband's Bain-managed job ended. It's clear that the public, and even the pro-Obama media, is repulsed by the overwhelming dishonesty of this ad.
And
2) the selection of Paul Ryan as V.P.
