In this morning's Washington Post, Michael Gerson takes on Ron Paul, specifically his comments about legalizing drugs made during last week's GOP presidential debate. Gerson exposes the principal fault line in today's GOP, between its libertarian instincts and its social conservatism. There is no obvious way to reconcile these two positions. Alas, the Enlightenment freedoms celebrated by Congressman Paul have little in common with the freedom of the children of God celebrated by St. Paul.
