Actually, his citizenship IS an issue, whether he is Natural Born, is an issue for holding the office of POTUS.
If he is not naturalized, then he may not be a US Citizen at all, in any capacity.
There is evidence that he was adopted by Lolo Soetero in Indonesia, and then had a legal name change to Barry Soetero. There is no evidence that I have seen, and I have followed this closely, that he ever had a legal name change in the US to Barak Hussien Obama II.
Therefore, he may not be a US Citizen, rather an Indonesian citizen, before which he could have been born in Kenya which would make him a British Subject.
Nothing I have seen has proven him to be a US Citizen, Natural Born, naturalized, or anything else.
Thanks. You’ve followed it more closely than I have. I have no doubt that there is something there to find: Obama is trying to darn hide to hide his past. Any reasonable person ought to be trying to see what’s behind the curtain.
