Newt Gengrich, though he is not all good, has come out and said that we should not let the Muslims who believe in Sheria law into the USA. We must understand that Article 9 of the US Constitution says that the US Constitution is the supreme law of the land. Those who are for Sharia law say that such is the law for the whole world. Thus they are inherently anti-US Constitution, which means they are anti-USA, and truly should be kept out of the USA like any other person who is against the supreme law of this land.
