As I've stated on other threads, I prefer Thomas Hardiman, but suspect (and would be relatively satisfied with) the likely female nominee to replace Ginsburg, Amy Coney-Barrett.
At that point, Breyer will have to accept that his side is so far outnumbered already that he would no longer need to postpone his retirement hoping for a Democrat president/senate in the near future, and he'll retire too. Then hopefully Hardiman will take that seat, leaving only Kagan and Sotomajor for the socialists/statists, neither of whom seem particularly healthy. Trump 2020. (I hate to lose Justice Thomas, as he is our staunchest unwavering ally, but he's getting to that point as well...).
