Is McCain giving up

It’s really starting to look that way given the states he’s already conceding based on where his dollars are going.

Note that it’s not just Colorado on the chopping block, but also Minnesota, Wisconsin and New Hampshire. Michigan was conceded some weeks ago. Iowa and New Mexico are on life support. Essentially, McCain seems to be giving up on any path to victory that does not involve Pennsylvania — a state that we presently project Barack Obama to win by 9.7 points.
