Not saying he's ineligible, just that both candidates against the lawless one had questions about article 2 themselves. This was not just a coincidence.
Your point is moot. There was never a question as to Mitt’s ArtII status, there was however a question about his Dad’s ArtII status when he ran fro POTUS. Congress even debated the issue and it is a fascinating read if you care to. But he did not get the nomination so that debates became moot as well.
