I do see where it’s said that McConnell has said that - but I have not seen it myself.
This is what’s being said
“Prior to Ginsburg's death, she dictated in a statement through her granddaughter Clara Spera (a lawyer): "My most fervent wish is that I will not be replaced until a new president is installed."[153]”
it would be my opinion that if Trump wants to win this election - he’s just been handed a winning ticket
He’s actually showed humanity, sympathy and emotion from her death - finally- live
if he capitalised on that and said that out of respect for her wishes - he will wait for the election - he would get a huge swing and I think he’d race across the line
