I'm not saying they were right or I (not being elected or running for anything) would do the same. I'm saying that coming along later and beating them up for it is a little unfair.
Anybody who gets elected is part of the Establishment by definition, but Walker is better than most, and if you or I had been elected a few years back, we'd have done the same and would probably be getting abused as GOPe right now.
Again, you’re saying the only way to get elected is by advocating citizenship for the never ending horde of foreign invaders. If you believe that, I can’t help you.
