@MontereyJack,
right. Already, in the Texas case the 5 focus states have all sent communication to the USSC to remove their state from the case as assignees.
(We all know how that went)
As you said, it would take a VOTE OF CONGRESS and how many states have already voted FOR BIDEN and have certified their counts (And none of whom were targeted by Rudy's REVENGE)
I predict that 1 or 2"rogue electors" will vote the way they feel and it wont bear a jot or singl tittle.
