I don’t think it matters, even if the case implicates them red-handed. The electors have voted, and the electors elect the president. This is pretty much undoable at this point. It wasn’t always so, but we had too many cowards in charge.
Wrong! (again). Congress just unseats the members of the Senate and House seated as a result of the unlawful elections. Then it decides how long the state loses it's representation and terms of restoration of voting rights.
