Obama was born on US soil (Hawaii) to a US citizen mother. Obama is a Natural Born Citizen, there is no precedent.
Who says?..
The Governor Of Hawaii for one :
“You know, during the campaign of 2008, I was actually in the mainland campaigning for Sen. McCain. This issue kept coming up so much in the campaign, and again I think it’s one of those issues that is simply a distraction from the more critical issues that are facing the country. And so I had my health director, who is a physician by background, go personally view the birth certificate in the birth records of the Department of Health, and we issued a news release at that time saying that the president was, in fact, born at Kapi’olani Hospital in Honolulu, Hawaii. And that’s just a fact. And yet people continue to call up and e-mail and want to make it an issue. And I think it’s, again, a horrible distraction for the country by those people who continue this. It’s been established. He was born here.” —[former] Governor Linda Lingle (R-HI)
