Boehner and McConnell (along with Hillary and her posee) and their ilk are the reason people want political outsiders in. Trump is also still part of the problem. Cruz, Paul, Lee, Banks (my congressman), Amash and their allies are part of the solution.
I like the inclusion of Amash and to a lesser degree, Paul, but
Ted Cruz? How? That guy is a showboat who cares more about self-promotion and symbolic stands than actual solutions. His role in the 2013 government shutdown speaks to that, but so does his toxic relationship with his colleagues. And if he was so principled, where is he now, when Trump and Republicans just dumped a
massive pile of debt on this country for little actual return? The national debt was like this huge deal that we just couldn't move past just years ago, yet now no one even talks about it anymore. This is important for a "true conservative" like Cruz. Given all his other shortcomings, if he doesn't stick to his guns when the going gets tough, then he is nothing but a unhelpful, destructive partisan hack, which is actually less favorable than the standard spineless politician.
If anything, the Cruz types of the GOP are part of the problem. They only have strong conservative principles when a Democrat is in the White House, at which point they are willing to burn down the federal government via quixotic schemes they know are doomed to fail, all for reasons that are barely genuine at best. Then, when things get tough, they are no where to be found. It's really hard to overstate just how bad of an influence these kinds of politicians are.
