The GOP wants ANYONE EXCEPT Trump. Hillary, Col.Sanders, Rubio, Kasich they are all the same for the D & R establishments. Anyone but Trump and things continue as they have for years.
This is why I gave up on the R Party years ago, they are completely in bed with the Dems. Both parties are working together to protect their interests, to hell with this country. Hell, even if Trump wins nothing will change. The R's will not help a D POTUS and neither will the D's help a R POTUS. The only thing different will be that Trump will be opposed by BOTH parties effectively making Trump a 3rd party POTUS.
The sooner we get to the blood shedding, the sooner we can get things moving in the right direction.
