I think there's is little chance that they will rule to disenfranchise all PA voters. Act 77 was never intended to amend the constitution, it was meant to modify their existing election laws. I don't think that the legislature thought for a moment that it might require amending the constitution until Trump lost. I think he originally thought to delay until after the safe harbor as a de facto denial. But it is possible that Roberts or other Justices think it would be better to address it head-on to add legitimacy to the EC makeup. I think there is the smallest of chances that they overturn the vote... if that happens, the right can never again claim to have the moral high-ground with regard to "activist judges" (something I personally think both sides are guilty of).
