I think the biggest thing that would drive the left absolutely bonkers would be for President Trump to nominate Ted Cruz to replace her.
Oddly enough, he is regarded as a legal genius so could easily fit on the court. But there would be Democrats immolating themselves on the street at the idea. Their level of hysteria would convince most voters that a barrel of hyperactive monkeys would be better as elected officials.
Trump will nominate another woman to replace RBG.
My guess is the one already on the 7th Circuit Court of Appeals -— Amy Coney Barrett ( she was the one who gave Dianne Feinstein the fits and would do so again ).
Ted Cruz believes Anwar Al-Awlaki’s kids, born in Yemen to one American citizen parent, are natural born citizens of the USA eligible to be President.
(if he is, they are)
