It's a familiar refrain from politicians of the Tea Party persuasion: The country has lost its way by straying from the infallible guidance of our nation's founding documents. "We don't need to rewrite the Constitution of the United States," Herman Cain said on May 21, announcing his bid for the Republican presidential nomination. "We need to reread the Constitution and enforce the Constitution." He wasn't done. "For the benefit for those that are not going to read it because they don't want us to go by the Constitution," he continued, attempting to skewer Democrats, "there's a little section in there that talks about life, liberty and the pursuit of happiness." Unfortunately for Cain, that little section happens to come from the Declaration of Independence.
