No, not Ginsburg or Breyer (both of whom are holding on for dear life), but Thomas is also the subject of recent retirement rumors and if conservative talk show host Hugh Hewitt is to be believed, per a number of conservative luminaries Alito seems to be burned out and looking to exit DC.

I would expect them to retire during this administration of course, and that would mean Yurtle the Turtle will hustle them through in an election year, just like he said was inappropriate when Merrick Garland was nominated in 2016. The good news is that whatever FedSoc hack gets appointed to replace them, net lean of the court stays the same as those two are the most conservative justices.
