If his family can talk him out of running again (BIG IF), and if he can keep a low profile (even Bigger IF), then the country can move on. Unfortunately, his desperate desire for attention can be a pain in the ass, until he figures it out.
He actually did a lot of good things as the President, in spite of all the attacks he was fending off from all directions. Unfortunately, if he keeps lashing out, he's going to turn off his staunchest supporters and he'll destroy a decent legacy. I really hope he figure it out and takes all his frustrations out on a golf course.
