Interesting point. I doubt if the writers of the 14A meant to give Congress the sweeping power to declare anyone an insurrectionist, and so deny him an office.
But Section 5 could certainly be interpreted that way if you were so inclined.
On rare occasion the Supreme Court has limited the power supposedly given by the Constitution to Congress. So I guess anything is possible here.
In these Acts, Congress granted federal court authority to hear cases arising from these laws.
Should Congress declare presidential candidate DJT an insurrectionist (which isn't applicable per Section 3!) without granting federal courts the requisite jurisdiction, well, yeah we are in a real mess.
