Not a tall! If you are born in the USA (like Springsteen), or on USA territory, and both of your parental units are American citizens, voilà, you are a "Natural Born citizen."
If Obama was born in Hawaii, which is certainly a possibility, he still would not be a "Natural Born American Citizen," because his father was a foreign national, a subject of the Crown.
Hmmm, so many issues, so little time!
