I have no doubt. That 2004 speech at the DNC convention. Sometime after that he started getting his documents like his Selective Service registration squared away. (Those here on student-Visas didn’t have to register for Selective Service. hmmmm)
No this was before that. A magazine article. I remember reading it at the parents place in 2003-4 and it really seems like it was a couple of years old then. They were talking about state senate candidate obama.
