It all comes down to Lady Lindsey on the SJC and Mitch the Bitch. There is History, he stopping Garland during the lame duck obummer and no one would convince me that bidet isn't a lame duck right now, in terms of his electability in 2024.
That trick won't work this time, for several reasons. First, the democrats control the agenda of the Senate, so there is no possibility of denying the nominee a vote. Second, the filibuster doesn't apply any more - McConnell got rid of that for Gorsuch - and Kameltoe gets the deciding vote, so the democrats have the votes to force whomever they want through, so long as either Sinema and Manchin go along - I have no doubt they will except in the case of a raving uber radical - or Sinema and Manchin can be replaced with Romney and another RINO TBNL. Third, even if the GOP could stonewall this nomination, it will be taken as clearest evidence that the GOP is only interested in playing politics with the Court, and they will jam through a court-packing plan in response.
All told, Biden will get a nominee approved; the GOP's role will simply be to play the Kavanaugh card and give as good as they got during Trump's administration.
