Remember how President Obama was like, "Hey, guys, I was born in Hawaii," and everyone just accepted it at face value, and that was that? It's because of this complete lack of attention paid to Obama's origins that Michigan state senator Tom Casperson still, to this day, can't say for sure whether Obama is a natural-born citizen:
“I don’t know because it seems like that issue was dropped immediately as far as the major media went,” Casperson said. “My gut tells me if it had been a different president, say George W. Bush, they’d have been digging into like there was no tomorrow and trying to get to the bottom of, which they never really tried to get to the bottom of."
Consequently, there's no evidence, and we'll never know the truth.
