I suppose if she died tomorrow, God forbid, the president would probably try to replace her before the election.
We know that Mitch McConnell wasn't serious when he said that the president should not appoint a supreme Court Justice in an election year.

We have 50 states, with 50 state supreme courts.
Guess, how many of those states give their governor the sole rights to nominate a new judge, with the legislature having the power only to approve or disapprove?
