CNN's John King says the McCain camp has given up on Colorado alongside Iowa and New Mexico.
They are now finishing with a very risky strategy. Win Florida... Win Nevada, that is a state that is now critical to the McCain math even though it is only five electoral votes. And here is the biggest risk of all: they say yes, they have to win North Carolina, yes, they have to win Ohio, yes, they have to win Virginia— trailing or dead even in all those states right now—but they are betting, Wolf, on coming back and taking the state of Pennsylvania. It has become the critical state now in the McCain electoral scenario, and they are down 10, 12, even 14 points in some polls there...I hate to give free advice to McCain, but this is lunatic. The RCP average for Pennsylvania is +11.7 Obama. Pollster.com has it at 15.2%. Nate Silver puts McCain's numbers in PA at 2%.
How bad are McCain's internals in Colorado, if he thinks he has a better chance in PA? He has no chance in PA.
FYI: if he does win PA, I will personally burn both Neil and Srinivas in effigy. Sujata too.
UPDATE: Nick at Cogitamus points at one thing that distinguishes Pennsylvania from other potential McCain last-chances: no early voting.
Presumably this has something to do with information based on Colorado's early vote totals; the McCain campaign must believe that they can't achieve a large enough Election Day victory to offset Obama's advantage in early voting.Of course, Pennsylvania—Pittsbugh and Philadelphia with Alabama in the middle, in Carville's famous phrase—is also more ripe than Colorado for racially coded campaigning, as Shankar points out in the comments.
