They were totally just waiting for CA's polls to close.
I hope they didn't just pull a Dewey/Truman.
Edited to add:
McCain's concession speech was very good. I really feel so bad for him. He's been wanting the Presidency for at least a decade, probably longer...and with this concession speech there is no hope that he can try again in four or eight years like in 2000. This is it. He will not realize his dream. That must be extremely painful. I'm rather amazed he was able to be as collected as he was.
People are crying with joy that Obama won. All over the place. That sort of passion is so beautiful! His win means so much more for the American people than McCain's ever could.
I am so happy tonight.
