This Supreme Court nomination brings back discussion of Bork because the left would like to see something like that happen again. It's the model. Of course, they had a majority and were still the dominant party then. The memory is that Bork lost for being extreme. I recall a little history and can suggest a different reason.
The reason Bork was demonized was simple payback. He was in Justice during Watergate. Nixon told Elliott Richardson to fire Archibald Cox (special investigator). Richardson resigned. Next guy down resigned. Bork agreed to do the firing at the behest of Richardson and his lieutenant because someone had to do it lest a full-blown constitutional crisis emerge. That act earned Bork everlasting enmity from the left.
Some commenters will ask why I'm making a post out of a response I gave to comments earlier. The answer is, "I feel like it."
