Newt Gingrich, Sarah Palin, John Boehner, Jim DeMint and some Tea Party types don’t merely yearn for the country they idealize from the 1950s. They want to go back to the 1750s.

Joe Miller, the Palin-blessed Republican nominee for Senate in Alaska, suggests that Social Security is unconstitutional because it wasn’t in the Constitution. The Constitution is a dazzling document, but do these originalists really think things haven’t changed since then? If James Madison beamed down now, he would no doubt be stunned at the idea that America had evolved so far but was hemming itself in by the strictest interpretation of his handiwork. He might even tweet about it.

Evolution is no myth, but we may be evolving backward. Christine O’Donnell had better hope they don’t bring back witch burning.
