Different times, different candidates, and different campaign styles, but the resemblance is striking and powerful. Obama is 100% in charge right now, and the only question going around for McCain is if his campaign/debate suspension and is mistake, or the biggest mistake in modern presidential political history. And with only 39 days until the election, there is very little time left for McCain to change the momentum of this race. But if this pattern holds up, expect more drama from the McCain campaign all the way until election day.
EDIT: McCain sure made Dave Letterman mad. He really gets funny a little after at 6:00 when Dave catches McCain doing a live interview at CBS (in the same building), rather than being on his show, or being in DC like he said he would be.
