RIP, RBG. Sympathy and condolences to your family.
I'm quite sure that the Democrats already have affidavits, depositions, and sworn statements attesting to the most grotesque and perverse criminal behaviors imaginable from Trump's nominee to replace Ms. Ginsburg; they just have to wait for Trump to officially nominate someone so they'll know whose name to fill in on those affidavits, depositions, and sworn statements.
RINOs may be a problem - Murkowski, Collins, and Romney may decide against voting for any Trump nominee before the election or in a (potential) lame duck session afterwards. If McConnell and Graham don't push a Trump nominee forward, a LOT of GOP voters will regard this as a deep betrayal of trust and either stay home for the election or (shudder) vote Biden, just out of spite for being backstabbed (again!) by the GOP leadership. And if things DO move forward, look for antifa/BLM to make things sporty again.
And of course, ABCNBCCBSCNNMSNBC will be hysterical for the next month and a hall no matter what.
Bumpy road ahead . . .
