"Gödel's Loophole is a supposed 'inner contradiction' in the Constitution of the United States which Austrian-American logician, mathematician, and analytic philosopher Kurt Gödel postulated in 1947. The loophole would permit the American democracy to be legally turned into a dictatorship."
Gödel never revealed the nature of the loophole, and it's never been discovered, though there are theories.
My guess: It's the Presidential pardon.
