It’s not a campaign for Obama. He is a complete adherent to the surveillance state. The campaign is for the sort of people who read the New Yorker and can be swayed by a man pretending, expertly, that he’s an expert at something he isn’t an expert in. With a little luck, the establishment thinks, the people who think that the NSA broke law in so monstrous a fashion it needs to be burned down and rebuilt from the ground-up, will be reduced to cranks because, after all, all the Serious People™ reading the New Yorker will be in agreement that he isn’t one of those good leakers that, presumably, leak things the establishment doesn’t mind being leaked.
Presumably, a few years of close scrutiny by the imminent Trumpenreich ought to change a few minds.
