Bill will eventually claim that he was threatened and blackmailed by Obama. (I hope).
More likely Bill will ultimately contradict (’innocently’, of course) the official version just enough to cut Obama’s legs out from under him. Then, while Bill grins cherubic-like, rambling on about what a loyal team player he is, Obama will twist in the wind. Bill is a sly old dog. He’ll do this thing right, with nuance and finesse, imho.
