We'll probably have at least two vacancies before 2020. I'm thinking Kennedy and Ginsburg. I suspect Ginsburg will try and hold out till after 2020, but she's already 84 and pretty frail.
Kennedy has already shown signs of wanting to hang it up pre-2020.
Ginsburg...man I just don't know. My great grandmother was 4 foot 10, sinewy just like Ginsburg and lived to be 99 years old, fiesty til the very end.
Those women like that just hang in there. With modern drugs...she might have another 10 years in her, as crazy as it sounds.
But yeah, if Trump can appoint 3 Justices within his first term...fucking home run, no question about it.
