Obama's birthplace changes as documented on the UPI.com website in the fourth paragraph. On 7 July 2009 the website carried a story published on 4 November 2008 claiming that Obama was born at the Queen's Medical Center. However, on 8 July, the same site scrubbed Queen's from the story and changed it to Obama's birth at Kapi'olani Medical Center. These are two different hospitals and the story was revised after a news report revealing Obama's birth reported at a different Hawaiian hospital. Web sites changed their information shortly after a White House statement claiming Obama was now born at Kapi'olani. Previously, the Snopes.com web site had changed their version as well.
As interesting as the actual birthplace is, and it still may be that Obama was born in Kenya after all, and not Hawaii, the real issue is his lack of status as a natural born citizen. If his father was a British citizen he does not qualify as a natural born citizen according to the Constitution.
