Every time Trump supporters refer to Boehner, McConnell, Bush, the establishment, etc., we should keep in mind that they're doing nothing to explain why we should prefer Trump over Rubio, Walker, Cruz, Fiorina, Carson, and other candidates who can't rationally be placed in the same category as Boehner, et al. Punishing somebody like Walker or Cruz by supporting Trump instead, because you're upset with people like Boehner, makes no sense. If you're upset with Boehner, then do something about it in Ohio or in the House, not in a presidential campaign. When you get upset with your representative in the state legislature, do you normally take it out on gubernatorial candidates who have no significant connection with your representative in the legislature?
Besides, Boehner is far more reliably conservative than Trump. That's not because Boehner is so good. It's because Trump is so bad.
