Momentum

Chuck Todd on the momentum in this campaign:

"All the trend lines are pointing in Obama's direction. This should really scare the McCain campaign. This thing -- it's at a tipping point. And this debate, frankly, is coming at a good time for McCain because he needs something -- anything -- to stop this Obama momentum. ... The pressure is all on Sarah Palin, not just for her own persona, but to save the McCain campaign ... I think Virginia, frankly, is a trailing indicator of the national numbers. ... John McCain is campaigning in Missouri later this week. That's not a good sign. You shouldn't have to be worrying about Missouri at this point."
