Boehner’s punishing of people that disagree with him has gotten out there. They are brave enough to talk about what he does if you don’t vote his way. The people don’t like this and are becoming informed.
Actually, it seems like Congress is becoming informed.
Trump has made clarity and honesty rewarding again. Congress grouses and grumbles occasionally, but it seldom bucks leadership to the point of ousting the leader. They are polling differently now. I do think it is a page from the book of Trump, myself. Hope it holds.
