I don’t think it matters what happens in the MISC. If they reject Stein, Goldsmith will slow walk the decision on stopping the recount until Stein files another motion on some other grounds with him. Recount will be finished by the time all this is wrapped up.
Maybe. BUT, the recount now has no legal force regardless of how it turns out, and Goldsmith cannot change that fact simply by allowing it to continue.
Congress can (and should) remove the lower Federal Courts’ jurisdiction from all recount issues.
Any appeal that challenges the state courts should go direct to SCOTUS. Time after an election is of the essence.
