If Stein goes to the 6th Circuit, it would be to appeal the recent decision of the ED of MI district court. basically her argument would be that recounts are a matter of constitutional right.
The dissent in the MI Supreme Court decision to deny hearing her case is a template for arguing something slightly different to SCOTUS.
She has already made a complete fool of herself. In for a penny, in for a pound (as opposed to not sending good money after bad, a cliche for every occasion!)
Her problem with filing an appeal from the District Court Order (aside from the obvious one that her case is frivolous) is that December 13 will have come and gone long before the Court could issue a ruling. Federal Rules of Appellate Procedure govern the hearing of an appeal.
