That’s not what the law said at the alleged time of Obama’s birth. The mother had to be at least 19 when she gave birth to confer US citizenship to her child, unless she gave birth within the US. Given that there is no legally-valid birth certificate for Obama in Hawaii, chances are very good that he was born outside the US, and if the dates and parentage are as claimed on his non-valid HI BC, then his mother was NOT old enough to confer US citizenship to a child born outside the US.
You are correct. Many here per the comments still don’t understand the actual law. Ugh. But again, you are correct.
Buttah! How the heck are you? Good to see you, happy new year, I just wrote the same thing before seeing your post.
