If I understand correctly, your analysis is based on who they’re endorsing. Or, do you believe they’ve supported the establishment agenda?
I don't think Mark supports the establishment. I'm not sure about Rush (and I've been a big fan for years). I've lost great respect for both during this primary. I can respect Mark liking Cruz. I liked Cruz very much early on. But Mark has put blinders on to every questionable deed done by Cruz and he has poured buckets of gas on any little spark around the Trump campaign as well as played lose with the truth.
I'm really not sure what's driving Rush but my ears and common sense tell me he wants Trump to lose.
Either way the end result is the same. They help the establishment by dissuading votes away from Trump and ultimately leading to a brokered convention where God only knows what will happen. But it sure won't be Cruz or Trump . There is no way Ted Cruz is winning the nomination outright. The math just doesn't support it. That only leaves the choices of a brokered convention where the establishment wins or an outright Trump win.
How Rush, Mark, and many here don't see that is beyond me. I can only hope that someone named 'Optiguy' can see it.
