There's the rub. Up until the debate, Romney had failed to present himself as a "good option". He'd been running almost exclusively as "you don't want to vote for that guy again, so I'm the other guy". Romney really did a nice job showing why someone would want to vote for him, and not just because he's not Obama. Romney's bounce would have been good just for his strong performance. Obama's poor performance just made the bounce higher.

I'm not sure I believe an 18 point swing in women either, but I bet the Obama camp is going to take it seriously. That's an important demographic for the POTUS, and an area where Repubs, and Romney, have been vulnerable.
