Ben Smith at Politico: McCain's move was political

Ben Smith at Politico echoes what many are thinking - John McCain put John McCain first, as he always does:

McCain suspends his campaign, and asks to postpone Friday's debate, to address the financial crisis.

Both candidates have been marginal players; McCain, though, seems to have the potential to make himself a major one, and his move is a mark, most of all, that he doesn't like the way this campaign is going.

But in terms of the timing of this move: The only thing that's changed in the last 48 hours is the public polling.
