If he survives this onslaught and gets reelecyed it will be because he has beaten them to the point of weakness. They’ll whine and fight but will be much weaker.
The Trump Derangement Syndrome we have seen up to now will not merely go into overdrive, but proceed up to warp speed and beyond. If you think they have just about dragged in the limit on silliness and faux outrage, be reminded that there is NO theoretical maximum on those two aspects of human imagination.
They really, really want to impeach Trump for SOMETHING. Nothing is as vengeful as a bruised ego that has evolved beyond logical thinking and calm discourse.
