• Every individual state has the right to determine who can run for president in their state (this would be a complete clusterfuck but very funny to watch if you’re not American).
• Separation of powers. This is an ambitious growth in the courts powers in determining who can be in the executive branch. They need a motion from the legislature to confirm that they have this ability.

I honestly believe that conservatives on the supreme court are going to look for a way not to rule on it. The legal case for insurrection is straightforward, and they’re going to want to just make it someone else’s problem.
