The long view is that Donald getting re-elected is most important
If ACB is not confirmed, Donald will have more shots at filling the SCOTUS seat and will also (likely) be able to block the court packing threatened by the Leftists.
If he gets her confirmed but loses, the Supreme Court will be irrelevant as the coup marches on.
Court packing requires a Constitutional Amendment. No way will 3/4s of the States say yes. You also need 2/3s of the House and Senate. I doubt that the Satanists will get a 2/3s majority any time soon in either house.
