McCain -- Comeback?

Why is McCain's victory a "comeback?" He hardly campaigned in Iowa and took 3rd. He campaigned hard in N.H., where he won the 2000 primary primarily because independents are allowed to vote, and subsequently won. He's been a front-runner there for a long time. This is the first primary...there have been no "comebacks" by anyone and the race is still wide open.

Paul Mirengoff at Powerline commented on his excellent victory speech and I find that I agree.
Compare to the Democrats' victory speeches...
