Bill will do ANYTHING to make sure Hillary doesn't run/win.
He is so self-centered, he must be the center of attention all of the time. Hillary be damned.
He would LOVE to be the first 'FIRST HUSBAND' in US history.
His megalomnaniac, narcissistic, ego would be stroked (no pun intended) more than anything else he could do in the remainder of his life. He would REVEL in that historical role.
