When Robert Anton Wilson ran for governor of California in 2003, the central conceit was that most of the people who oppose restrictions on guns are right wingers, and most of the people who oppose the "war on some drugs" are on the left. So by opposing gun laws AND drug laws, a libertarian coalition could be formed.
Jacob Sullum, a writer for Reason magazine, is a writer I read often because of his reliably accurate news and commentary on the war on drugs. He also writes a lot about gun issues, although I am less interested in that issue and read those pieces less often.
In the course of a Twitter/X thread to promote Reason's current fund-raising webathon, Sullum reveals that he's working on a "guns and dope" book: "After 3 decades of covering drug & gun policies for@reason, I am writing a book that explores these themes, showing that left-leaning critics of the drug war and right-leaning critics of gun control, despite their ideological differences, share many of the same concerns."
It should be an interesting book.
