Lamenting over that is not what I'd take away. What to take away from all that impeachment BS, imo, is that the Dims have provided the blueprint to stop all future presidents from getting anything done.
Of course, this blueprint doesn't work on Trump. They counted on him caving, as if he was Jeb Bush, or someone like that. But instead, he just powers forward with the business of the American people, and making America Great, no matter what BS they pull against him. And that is what really drives them crazy.
