Sorry DUmmie, but for Obama to be born outside the USA and be a citizen, both parents have to be US citizens. If he was born outside the USA and only one parent was a US citizen, then he is toast.
I went thru all this hassel with my X-wife. She was born to a US soldier and a British bride in Germany. She was both a German and a British citizen by birth but not a US citizen when I married her. She can never be president.
