This is disappointing, but my inference is that the McCain campaign believes Pennsylvania is a more likely pickup and intends to double down there.

If McCain takes Pennsylvania but loses IA NM CO VA, he wins 273-265.

But if McCain took Michigan but lost IA NM CO VA, there would be a 269-269 tie and Obama would win in the House.
