Reason for (Cautious) Optimism

I'd like to throw out one more reason besides the lopsided sample that's reason for some cautious optimism.  Keep in mind that over the summer, Mitt Romney has basically taken tough punches from the Obama campaign without really fighting back. Soon, he and 527's will begin to spend the money that's been raised, even as Obama's campaign has started spending more than it's taking in, two months in a row.
