I think that's the plan. It was the plan last election. It didn't work but it's still the plan IMO.
I suspect it isn’t going to work this time around either. The Party isn’t going to be united behind whoever the nominee is I fear.
I get the impression from many that they would rather see President Hillary if they can’t get their candidate nominated. It is the same kind of thinking that some German political parties voted with Hitler thinking they could either control him or he would be weak and they could then replace him with their own.
