Sadly, Cain’s Bachmannesque ignorance of the nation’s founding documents makes him well-suited to compete in a GOP presidential primary. Republicans invented an utterly meritless constitutional objection to the Affordable Care Act, they’ve called everything from Social Security to Medicare to child labor laws unconstitutional, and they’ve even pretended that the Constitution allows them to strip Americans of their citizenship. So Cain needs to look no further than his own party if he wants to find people who are more interested in rewriting the Constitution than in actually reading it.
