Another worry I have and has not been stated above is this:
Biden wins but Republicans keep 51 in Senate. After the election Mitch argues that the nominee should be somebody acceptable to both Biden and Republicans, and they end up choosing somebody right of even Garland.
I suppose this is somewhat parallel to RGB's nomination too since she was on Orrin Hatch's list to Bill Clinton, but people are much more careful in dissecting a nominee's past now.
I share your concern. In which case, the Biden Administration needs to reject McConnell's demands. Given demographic trends, the Senate is destined to become an illegitimate, undemocratic body. At some point, CA and WY will no longer have the same number of Senate seats, or influence over SCOTUS appointments. Better to force the confrontation now while there's still time to preserve democracy and curtail climate change.
