And finally for one last thinking outside the box choice, how about Gov. Camacho of Guam?
Is that even legal?
Camacho was born in 1957, after Guam Organic Act of 1950 made everybody there citizens, so he certainly qualifies as a natural born Citizen. The only potential fly would be if the Supreme Court ruled that the fourteen year Resident requirement only pertains to incorporated territory or whether residence in an unincorporated territory such as Guam counts. If it is only the former Camacho might be shy of the necessary fourteen. (He was educated at Marquette and was in business from 1980-1988 (either in Guam or Stateside, I don't know which) until he followed his father into Guamanian government and politics. His father was an Army dentist at the time he was born, so he may also have some time resident in the United States from then depending on how long that lasted. I'd be inclined to count time spent in Guam since the passage of the Organic Act (or any other territory where all native born persons are U.S. citizens) towards the fourteen year residence requirement, but who knows how the courts might rule. Possibly the Court would that such a question is a political rather than a judicial decision, which would leave it up to Congress to decide. Given the brouhaha that deciding against Camacho would raise politically, I can't see Congress, regardless of whether in Democratic or Republican hands choosing to disqualify Camacho on those grounds.
