They did the right thing.  And there isn't any payback, because all McConnell has to do is use the "nuclear option" and Gorsuch will be confirmed with a simple majority.  It's really just a whole lot of partisan noise and crying that will not amount to anything.  
They should have saved their fight for Ginsburg's replacement.  
I dunno. I feel that there was plenty of time to vote on an Obama nominee. 
Nothing wrong with Gorsuch at all, but I don't think they should have not held a vote. The time that this took to get anyone to a vote is pretty unprecedented. 
I do feel Obama's pick should have had hearings and a vote at least. Then if blocked, they can say they weren't obstructionist. 
Surely the GOP was being so in not evening calling for a vote for the Obama nominee.
