Reagan had to deal with the 60 vote filibusterer rule. Trump does not.
If the dems had a third of a brain, they would have worked out a deal during the Gorsuch nomination—we (the dems) will give you a painless/easy/quick confirmation in exchange for an agreement that the NEXT appointment (knowing that kennedy,breyer, and of course RBG could very well be replaced during the trump term) require a 60 vote confirmation.
That of course would have required foresight on their part. If they didn’t do something like that with Gorsuch then they for sure should have done it for the Kav nomination KNOWING that RBG is almost in rigor mortis and breyer is 80, so at least they could have had some leverage for future picks.
but no, they probably really believe/d that Trump will be impeached.......
