I’ve heard that Bill doesn’t really want Hillary to be elected president.
He would then have to move back in the White House, and pretend that they are one big happy family.
His comings and goings would be under much more scrutiny if they were back in the White House.
He would be in the White House but not be the top banana this time around. Would he really be happy as First Lady?
The Clinton foundations activities would be affected and subjected to more scrutiny if they are back in the White House.
The cunning Clintons figure the positives outweigh the negatives you outlined.....they will have access to the US Treasury to payback all the people they are beholden to.
Plus Hillary will get to wield the presidential pen.....and there’s so many Clinton cronies who need pardons.
