I believe Biden was judiciary chair when it came to Bork and Thomas’ confirmations. You can’t underestimate that as a reason for them hating him. Gosh it’s bad enough that we have Scalia, Thomas, and Alito. Can you imagine a USSC that had until his recent passing: Scalia, Thomas, Alito, and Bork? Bork is the big reason I don’t want to hear from wingnuts about “extreme liberal judiges” ever.
