Breaking news: reason subscriber Mike Gravel, who when last spotted was still running for president as a Democrat, has just joined the Libertarian Party. Commenters are invited to debate the relative merits of a Barr/Gravel or Gravel/Barr ticket.
In other LP news, Mary Ruwart, whose book Healing Our World presents libertarianism with a leftish, new-agey slant, has entered the race for the LP's presidential nomination. So...Ru/Paul? Ru/Barr? Barr/Chong?
Update: Gravel definitely wants to be the Libertarian presidential candidate. No word on whether he's willing to settle for second billing -- or if he'll stick around if the party rejects his bid.
