From what do either of you base your opinions on, that says the reigning King of Thailand or the current Dauphin of France, are eligible to be the Commander in Chief of our armed forces?
I don't think either of those people were considered to be American citizens at birth. Either way, Obama had a parent (his mother) who was a US Citizen (or are the birthers trying to cast doubt on that, too?!), so these are totally different cases. Furthermore, neither of these people has ever claimed US citizenship, nor lived as a US citizen. Do they have a US passport? Obama does.
That raises another set of questions that have been discussed here on FR ever since Obama became a serious candidate for POTUS. For some reason, Obama's passport records have never been publicly released, so we don't know, for example, how he might have obrained such a passport, how he traveled abroad to Pakistan during his college years and how he traveled to Kenya a few years later.
Do you think Barry/Obama is a "natural born Citizen" because he was (allegedly) born in HI? Or do you think he is a "natural born Citizen" because his mother passed her citizenship to him?
