Got a press release about this earlier today from Gary Johnson's campaign. This is big. Norquist is a very respected mainstream figure. Dozens of Republicans have signed his anti-tax pledge. I know it's not an endorsement or anything, but just participating with Johnson in a townhall like this lends him a lot of credibility. He's already shaping up to be the most credible, well-credentialed third party presidential candidate in recent U.S. history.
