"In my view we have got the lead and the ball and now it is a matter of executing the final ten days of the campaign. Governor Romney profited from that first debate primarily by recouping those voters who he had lost in his dismal month of September when they had such an uninspired convention and when the 47 percent tape came out. But that is all that happened. We've had two debates since. I haven't seen — in the things that I have looked at — I haven't seen momentum since that time. I think the race has settled in, and it has settled in with us with a small but durable and discernable lead in these battleground states both in the aggregate and individually. The question is how does he change that dynamic now? There is no big intervening event," – David Axelrod.
