Tennessee's State Senator only wishes we don't. That's the same as stating we don't need the Constitution anymore.
I recall at least three different Kenyan parliamentarians stating in the minutes of the Parliament that Obama was born in Kenya. But I don't recall any of them evincing any knowledge of the Natural Born Citizen clause in the US constitution, so as to question the legality of his being POTUS. Rather, they merely congratulated and praised Obama.
