You present the crux of the dilemma of this whole argument. If ‘jus soli’ is the one and only birth criteria then every ‘anchor’ baby has the right by birth to be POTUSA, as long as such person plays their residence time appropriately. Expediency and choices for any particular person beyond the recorded deliberations of the Founding Fathers does not serve the intentions of the Founders; it can certainly lead to cases like Obama’s. Being in much the same situation as Rubio I can relate to his but I can accept my status as ineligible even though a vet of WWII.
Thank you for your service. I'm eligible, but my child, having been born of myself and my non-naturalized alien spouse is not, so I can empathize with you to a certain degree, and also accept the situation.
There are over 300 million citizens to choose from. Surely finding a suitable and eligible candidate for the Executive from such a pool can't be too hard.
