I 100% guarantee they'd still vote for Trump even if he does successfully start WWIII, start firing nukes, and get the world destroyed. Send them back in time *after* watching their families and all of civilization die and they'd still refuse to vote for a black woman.
No doubt they'd think they could change him or something. And then the same thing would just happen again...
