Because the military industrial complex being 100% against him would cause the media and banks to be 100% against him, which would ensure he would not get re-elected. So he had to play it quiet on the anti-war stuff while pretending to be with them. But now it's becoming clear he might not get a second term, so all those cards he was holding to play next term, he's playing now. Better late than never I guess, but still quite disappointing I agree.
