Trump has tried to get employees of State and Defense not to testify in the impeachment probe. They have been testifying, and the result has been devastating. Impeachment is moving forward and at least half of Americans are in support. Even if it’s not immediately fatal, it will ultimately fatally wound him.
The subpoena action is moving forward. NY prosecutor will win the appeal. Trump needs to win at the SCt, or his returns will be produced to the DA. It would not be easy for the SCt to throw Trump a bone here. They may do it, but it will not be easy, and there will be consequences.
25 GOP House members acting unruly is nothing. Just a show that will only increase the resolve of witnesses, the committee, and likely the Senate.
Trump is Really unpopular, and independents are starting to get it. Importantly, the people among whom he is popular are the people whose power is rapidly decreasing, mainly the old and uneducated. This is the last stand of the idiocracy.
That’s not to say that Trump has not done lasting damage, especially to the courts (allies will get over Trump, but because he’s an aberration and it’s in their interest to), but we always knew he would do lasting damage. The good news is that the system, with some significant exceptions (lol, Barr), is working and he will be crushed.
