First, a moment to brag that I called it right today that Huckabee and Obama would win Iowa. The only visual proof is this screenshot from Facebook:

Beyond that, though, I was just talking with an Obama organizer in Iowa who said: “I’m here with our precinct field captains and these are people who haven’t changed the world in a long time and they’re really excited tonight.”
It’s a huge win for Obama. There’s no other way to spin it.
