IMO Jeb Bush running quite simply guarantees a Hillary win. No matter how crappy the travails of Hillary between now and the election; no matter how untrustworthy the accumulated load of all that crap ends up painting her, if Jeb is the GOP nominee and Hillary is not in Leavenworth, she will win the election.
That would be a great slogan for her: Hillary!! Stay out of Leavenworth!
.....”Jeb Bush running quite simply guarantees a Hillary win”....
Well, that is the purpose of Jeb in the race.
