It looks like Ron Paul will run for president again, though this time as a Republican (he ran as a libertarian a while back). Don't let the "Republican" tag fool you. He is the same libertarian, but this time he is going to try to shake up the Republican party. (Here is his web site)
This is great news -- particularly given that the Republicans turned on the libertarian wing shortly after the last election (presumably they feel they lost because they were not statist enough). It is thrilling to see a legitimate, non-fruitcake libertarian candidate running on a major party ticket.
This could make the Arizona primary, which is early in the race, a real event. Arizona's Republican party nabobs are strong McCain guys. Pitted against McCain and the party leadership is a Republican rank and file that has a strong Goldwater-libertarian streak and that is a bit tired of McCain's shtick. This may be the first primary in years (maybe ever) that I have gotten excited about.
