The first three paragraphs of the article spell it all out.
Who knows what will happen in the next fours weeks -- the tide could easily turn the other way -- we have two unusual men running for president.The Pew poll is devastating, just devastating. Before the debate, Obama had a 51 - 43 lead; now, Romney has a 49 - 45 lead. That's a simply unprecedented reversal for a candidate in October. Before Obama had leads on every policy issue and personal characteristic; now Romney leads in almost all of them. Obama's performance gave Romney a 12 point swing! I repeat: a 12 point swing.
Romney's favorables are above Obama's now. Yes, you read that right. Romney's favorables are higher than Obama's right now. That gender gap that was Obama's firewall? Over in one night:
Currently, women are evenly divided (47% Obama, 47% Romney). Last month, Obama led Romney by 18 points (56% to 38%) among women likely voters.
You can't blame anyone but Obama for his performance.
I read in a NYT article that his campaign management was already plotting the new strategy during the debate -- while he was still on the stage.
