A state case with federal implications as well as Constitutional issues is indeed the purview of the US Supreme Court. Look at State Gun laws and cases as an example. You can pass any state law you like that isn’t proscribed by the US constitution, but you can pass laws or pass judgement in a manner that goes against the US constitution. The myriad constitutional violations in this bogus case are expressly enumerated in the US constitution so you have a federal concern here.
There are numerous Constitutional issues, probably 4-5.
The Jury instructions were Constitutionally defective.
The NY Court of Appeals is a joke. That’s like holding out for Hochul to be fair and law-bound.
The Truth is the SCOTUS would have interceded long ago if this was Hillary or Joe. You think they’d watch a Prosecutor run on putting Obama in jail and then let totally unprecedented charges be used to get him?
Justice is far gone, and SCOTUS just wants Trump to go away. Now they love them some Biden, Schumer, and Pelosi rhetoric.
