Of course the system is rigged against outside candidate. Why do you think Jeb said he could lose the primaries and still get the nomination? Why is Kasich still in the race? Why did Ryan say that any of the candidates who ran were eligible to get the nomination?
The way Donald carries on, you’d think that the GOP was there for the good of the American people! The nerve!

(But if George Washington knew about this, he’d probably give Donald an attaboy for it. He hated political parties.)
