Benny, False. It started seriously with Democrat “borking” of Justice Bork in ’87 and nearly doing the same to Justice Thomas in ’90. For a while the Conservatives still went along with it eg 96-3 vote for RBG, but eventually realized it’s self and nationally destructive.
Conservatives looking to emphasize the dire state have often quoted left-wing Harvard Law Professor Mark Tushnet that “For liberals, the question now is how to deal with the losers in the culture wars…My own judgment is that taking a hard line…is better than trying to accommodate …Trying to be nice to the losers didn’t work well after the Civil War, nor after Brown [v. Board of Education]. And taking a hard line seemed to work reasonably well in Germany and Japan after 1945.”
