“Except for revenge for the way Trump treated Jeb, why would Bush want to go down in history this way?”
It’s not only that. President Bush called out every RINO Republican since President Reagan and all of their advisors and cabinet members, including most Congressman for selling out our country and the American people for decades. He called them stupid or corrupt or both. He did this all during his primary and afterward. All of DC despises our President for calling them out and for winning the Presidency with ZERO prior political experience.
President Trump is the kind of President the Founders had in mind. They never ever dreamed of Career Politicians. That is why there is no provision in the Constitution regarding career politicians. The Founders simply never envisioned the current state of our political class.
It wasn't Trump who didn't clap. It was those few of his own supporters who showed up to his rallies.
