It will go to the Supreme Court and they’ll rubber stamp so he can run.

The Supreme Court cannot issue a constitutional amendment, only the States or Congress can do that. It's going to be extremely difficult to claim the 14th Amendment doesn't apply to Trump based on the language and the fact that Confederates were barred from office without being convicted. The Supreme Court would be in breach of power to ignore what the Consitution says.

It would be pretty hypocritical given that a third of SCOTUS believes in the independent state legislature theory which pretty much lets states legislatures do whatever they want with regards to federal elections. But, that's probably not going to stop them siding with Trump.

And they will say that regardless of the Civil War precedents say, a court needs to determine whether he participated in the insurrection via a conviction.

Piecemeal
