I forget the legal term, but one cannot be prosecuted for breaking a law that did not exist at the time the newly defined "crime" was committed.
So, even if this were to pass, (which it wont) it wont do jack squat to anyone the DUmmies want prosecuted.
But, If, lets say, Obama does win the Presidency, he would be subject to it. This is a typical Moonbat publicity stunt.
