So long as ONE parent was an American citizen, an NBC can be born on Jupiter.
Birthers are people who have nothing to advance by way of real issues to support The Donald and so they fall back on irrelevant autoslime. The distraction is more effective than nothing.
Have you heard: Ted Cruz has sexual affairs with space aliens, so did his dad. It was in the National Enquirer (owned by a Trump buddy, natch!) so it just MUST be so. Then Cruz's crown just could not refrain from publishing ancient, near nude photos of Melania before she ever knew The Donald. That's another distraction. We are choosing POTUS not Sister Superior.
Can we get to actual issues now?
Actually, and factually, you are wrong. Whereas I have research which proves the meaning of natural-born citizen to at MINIMUM mean native born, you can produce nothing which refutes that. Even leftist professors concede that under the strict original meaning of the Constitution, the father would have had to have been a US citizen as well.
I have hundreds of hours of personally conducted research to support this, do you have hundreds of hours to support your claim?
Looking at the bills presented in Congress concerning natural born citizen, though not passed, will give you a perfect example of who is not a natural born citizen.
They wouldn't need to change/add something if was already in place.
The following proposed bill should give pause to BlackElk's assertion.
H.R.1380 - Overseas American Children's Human Rights Act of 1989
Why did the law need to be changed and why did `natural born' need to be inserted if they were already natural born?
