There must be a significant number of Republicans who are done with this president. Sure, they’re half-heartedly defending him, but they must think that it’s worth it to go along with the Democrats in punishing the whole country in order to replace him. It’s a real nightmare for everyone, but the government would NOT go through so much trouble for nothing. There are millions of secrets they are keeping from the American people in order to stay in control, but in the long run, they believe that it’s for the best.
One show on YouTube that provides context for why people do not like the president, is “Last Week Tonight” with John Oliver. Here are links to various relevant episodes. Warning: some language.
In one episode, the host mentioned that the American way of life would be threatened if the president started attacking our institutions. That might be why they think it’s time to get rid of him. Just a thought.
