I would just note that "...it was politically impossible" and "the Democrats were never serious in saying they wanted it" are two ways to frame the same reality. Both are true. Take your pick.
And then watched it get blown away by next congress as soon as the GOP gained 51 seats to do whatever they want. Blowing away the fillibuster is an awful, terrible, no good idea and there is almost no legislative agenda which would validate it.
And to be clear, the GOP senators were and still are slimey bastards for basically everything they did leading up to Gorsuch. It should have never been done. They will almost certainly regret it as soon as they lose the senate.
