Most voters had never heard of Paul before he launched his quixotic bid for the Republican nomination. But the Texan has been active in politics for decades. And, long before he was the darling of antiwar activists on the left and right, Paul was in the newsletter business. In the age before blogs, newsletters occupied a prominent place in right-wing political discourse. With the pages of mainstream political magazines typically off-limits to their views (National Review editor William F. Buckley having famously denounced the John Birch Society), hardline conservatives resorted to putting out their own, less glossy publications. These were often paranoid and rambling--dominated by talk of international banking conspiracies, the Trilateral Commission's plans for world government, and warnings about coming Armageddon--but some of them had wide and devoted audiences. And a few of the most prominent bore the name of Ron Paul.
