It's natural that disqualification under 14A should be a federal question, but it's nonsensical that SCOTUS would require Congress to enforce the Constitution. That was not predictable.
What the Dems did do when they had the House was impeach Trump for insurrection. If the Senate had done their job by convicting him, then, in the second phase of impeachment, he would have been barred for office for life. But, led by McConnell, they voted to let him be president again.
