He's flip flopped so relentlessly from the get-go that what he'll do is anyone's guess. The best thing he could do to build political capital is announce an end to the Clinton investigations. It would rank right up there with Ford pardoning Nixon, a move that will enrage the angriest partisans, but that will signal that the whole thing has gone on far too long and the country needs to move forward rather than drag itself down in perpetual recriminations. Also, there are things in his first 100 days agenda that he'll never pass without help from the Democrats since they entail going after the permanent political class, and dropping Clinton would greatly improve the odds of getting that done. He has some good things in there that the entrenched politicians on both sides of congress will oppose, but might find enough bipartisan support from congresspersons still willing to place the nation ahead of their own interests to get passed.

I didn't vote for him, but we'll see how it goes.
