As passed on through her granddaughter, she said before dying, my most fervent wish is that I will not be replaced until a new president is installed.
Not "until after the next election". Not even until after the 2021 inauguration. No, a new president must be installed. Her Supreme Court seat must be held open until at least 2025 when Trump is reelected.
Also, interesting word "installed". That choice makes it seems that she really didn't believe in elections.
I wonder what the granddaughter would say if the next president “installed” would be Mike Pence in 2025. Would she then say we need to keep the seat open until 2033?
