This is just my opinion, but I think Bush has found out that the criminality, and the illegal powers, of the klintons are so vast that they and their stooges cannot be brought to justice without risking a civil war. The klintons still have the FBI files (they probably get daily updates). They own all the establishment media, elite universities, and Hollywood. The klinton secret police, while now smaller, is still functional. Bill and Hitlery are still worshipped as gods.
Bush is not going to risk a civil war, which he has no guarantee of winning, along with a war against islam. I suspect he's resigned himself to the fact that 55% of the American people want things this way.
