If by some shocking outcome the Democrats get back the House PLUS 67 Senate seats...

1. That would indeed be shocking

Given that if the Democrats hold everyone of the Senate seats they currently have and won every Republican held seat up for grabs, they'd have no more than 58 (including two independents). And that's not going to happen.

I suppose in 2020 there is a possibility of enough pick ups to give the Democrats 67 or more Senate seats, although it's way too early to make such predictions.

And, no, the Democrats should not impeach Gorsuch since he hasn't done diddly squat that can be considered a high crime and misdemeanor. It a silly idea that no one in the Senate would spend ten seconds considering.
