Currently there is a diary at the top of the rec list entitled "I Don't Blame Obama." The gist of the argument is that Obama is not at fault for his actions because he is merely a part of the system. Notably: Any occupant of the WH would be against us, for any occupant would be a part of the system as well.
To me, this is a weak argument. I DO blame Obama. Yes, he is merely a part of the system. Yes, when he decided to run for office, he had to from the very beginning play their game, by their rules, or he wouldn't have made it as far as he did. A Howard Dean didn't make it. A Bobby Rush, who Obama ran against in his first Congressional campaign, certainly wouldn't have been allowed to make it.
But this is beside the point.
