I would have voted for him if he was the candidate and this was not an issue. I just don’t like the door that this opens up. Any radical can take an american bride, have a child in the M.E., raise and indoctrinate them there, and then move to the US and proclaim they are eligible to run for president. It has already happened. I think we are all pretty confident that it is exactly what happened with O. We elected a guy that was raised and educated in another country, in a belief system we are at war with.
The Constitution only requires 14 years of residence. That means we could legally have a president who is a natural born citizen, but who was raised entirely in another country. We could have a 65 year old who spent 50 years living outside the US. Clearly the Founders intended for such people to be eligible.
