I have ZERO faith that this Court has the balls to essentially outright declare that Presidents are exempt from the 14th Amendment, or to suggest that more bureaucracy (via Courts or Congress) is the answer. This leaves open too much of a possibility that Biden simply refuses to leave office. With more Democrats playing politics hardball, Habba threatening Kavanaugh, and Biden's recent scathing statements about Trump, they have to be very careful here. Sure they could have just refused to hear it, but Trump has lost some modicum of favor with the likes of the Federalist Society. This screams, to me, to be more of a symbolic gesture where they will attempt to legitimize the Court by ruling that this is a State issue, in an effort to suggest they ARE ideologically consistent. It would be a fairly political neutral move at a time when the Court is facing increasing scrutiny. They can sort of reject Trump, and sort of uphold Democracy, formally.
That's just a hunch, though. Would it surprise me if they declare Trump God-King? Nope. About the ONLY thing that would surprise me is if they uphold Colorado's ruling and Trump is automatically disqualified from all States. Though given how badly the GOP establishment t wants Haley to be the candidate, it's not impossible. Just highly improbable.
The X-Factor is how comically sh*tty Trump Lawyers are. They will get absolutely shredded in arguments, so it will be plainly obvious that the Judges will rule based on their current biases.
