I don’t know why libs do what they do. All I know is that MI certified its electors, sent in the list. It’s done.
You should tell the state of Michigan that, because they don’t seem to be aware that a recount is pointless.
I think that you’re hearing second hand news that is inaccurate or incomplete. If it was too late for a challenge I don’t think that election supervisors would be gearing up for a recount at this moment.
