IMHO the elites want a reliable elite like Romney/Ryan, but they need a brokered to get the cutouts. All the other one contesting so far except maybe Jebula were merely to get votes away from Trump.
If Trump can get the 1237 the elites will have a very hard time stealing it.
The 'new normal' - - an assumption American political parties represent corrupt elites and that the people's Herculean task is to attempt to overcome their power - every now and then...
Like being in the USSR 50 years ago... our little vote against the corrupt machine.
