Yes, he was a dual citizen and I did question his birthplace until the Elizabeth Warren "native American" scenario played out in MA. I now think its probable that Obama claimed himself to be Kenyan whenever convenient to open some doors, just like Warren claimed to be native American. In any case, he is still a fraud and not eligible. Likely held a foreign passport and enrolled in college as a foreign student, both things that natural born citizens would not be able to do.
