To me this indicates McCain believes he is ahead and is OK with running out the clock.
Also McCain didn't say anything about keeping Gov. Palin off the rally and fund raiser circuit. After all Alaska is in terrific economic shape. Not being a Senator has it's benefits. :) Sens. Obama and Biden have to go back to Washington to “save face” and sit in their Senate seats squirming, counting the days until the election day as the Congressional calendar slowly crawls by. They can't dare leave, else the media will excoriate them.
