How did that strategy work for Hilary Clinton?
I think your mistake is in assuming that politics is static. It may be just anecdotal data from me, but I determine the mood of Democrats collectively from politicalwire.com. When Hilary Clinton made those comments in 2016 there were an enormous number of 'civility Democrats' who chastised her for those comments. Maybe the 'civility Democrats' just don't go there anymore, but I think Democrats collectively are no where near as interested in civility/bipartisanship as they used to be following on 8/9 years now of Donald Trump and they certainly don't care anymore about the opinions of media commentators. Of course, many in the media who went after Hilary Clinton were, not surprisingly, swept up in Me Too.
So, I don't know who you're expecting a backlash from anymore other than maybe Joe Manchin and some of the media who most Democrats now recognize only pretend to care about civility in order to criticize Democrats, people like Chris Sillyza.
