I don't think that the Clintonistas will go quietly, even if they need to hire Lenin's makeup artist to give her a touch-up before every appearance. If it becomes obvious that she requires replacement, hopefully it will be much too late to do anything about it.
Speaking of which -- what HAS she been doing for the last few days? It's unusual to take off 5 days in the middle of a campaign. Bubba's 70th birthday is the excuse but I suspect some surgery -- plastic or otherwise.
I think the Obama wing of the Democratic Party is ecstatic, of course in private. No one can dispute there is no love loss between the Obamas and the Clintons from 2008, and the party is split between two factions headed by each of them. Of course our MSM won’t report this. Who is the greatest beneficiary of a Hillary loss? Her loss destroys the Clintonista wing of the party forever, and in 2020 the Obamas are in full charge of the Democratic Party and Michelle will be its presidential nominee.
