This thing started due to the insanity and delusional thinking of Leftist after their loss. For the first six months of the Trump Presidency, for whatever reason, a reason nobody can explain, the American Left was convinced that if they could impeach President Trump, that somehow, some way, Hillary would become President. They had no real plan or program in mind to make this fantasy come to fruition. It was some kind of irrational, delusional, belief without substance. They wanted a do-over, a second chance to make things right. And impeaching Trump would make that happen.
But now that Trump has been President for over a year and the people have become acclimated to this fact, they are now starting to take a more sober and rational view of the situation. It is slowly dawning on them that impeaching Trump will accomplish nothing. And that Pence may actually be a bigger threat to the whims and perversions that the Left wishes to force onto average Americans than Trump is.
I am seeing more and more rational people on the Left coming out against this stupid Mueller circus. Of course the Leftist hardcore fanatics and the NeverTrumps continue to push it out of sheer spite. They want Trump impeached just for the sake of it, with no clear reason, and no clear goal in mind afterwards.
Much of this farce is Trump's fault mostly due to his inexperience in politics. Trump believed the lie. He believed that most people act in good faith for the best interests of America. Of course, this is not true at all. Partisan Democrats, turncoat Republicans, and entrenched bureaucrats, don't give a damn about the best interests of America. They only care about themselves, their positions, and their money.
The fact that Trump has finally realized this, the fact that Trump finally realizes that he cannot trust people he thought he could trust, and cannot depend on people he thought he could depend on, is the invaluable take away from this whole ridiculous Mueller boondoggle. And in that sense, it is the best thing that could have happened. The Mueller witch trial is what it took to finally open Trump's eyes as to what Washington D.C. is all about.
