First, my own opinion: It was a push, but a push is a win for the leader and that's Obama. Also, he pretty clearly showed that he has the cool and gravitas to run the country. I kept waiting for McCain to turn into McNasty, but I was disappointed that we didn't see Mt Saint Helens...more like Mauna Loa, a slow flow of anger and contempt from McCain, but it's getting general play.
Snap polls, with all the usual caveats, seem to be giving this one on points to Obama, despite my thinking.
On the other hand, this was (eventually) the foreign policy debate. If McCain can't take Obama on foreign policy, what IS he going to take him on? Economics? I just don't see it. And I expect the Palin/Biden debate to be nothing more than a train wreck after that Couric interview...sweet Jesus, I'm no longer certain English is that woman's first language.
If the last debate is economic and McCain continues to assert that the way to solve a 400 billion dollar deficit is to focus EXCLUSIVELY on 18 billion in earmarks he's gonna flunk Electoral Math.
