His parents immigrated to the U.S. seven years before he was born. They could have naturalized. Obama's parents were not immigrants. Barak Sr. was a British-Kenyan who stayed that way. SAD married the British-Kenyan and almost immediately after divorcing him, married an Indonesian. She's not exactly a loyal American citizen. The question was about the difference, and there's still a difference. I also mentioned elsewhere Obama may not have wanted to take a chance since he lacked the legal ability to prove he was born in the U.S.

They didn’t. According to the 1930 Census, they were both still aliens (and Mike was born in May 1930).
So yes, the FEC gave matching funds to a guy born to TWO British citizens.
