Gary Johnson, who is expected to announce his candidacy tomorrow in New Hampshire, is included, of course. He's the only candidate who has made marijuana legalization a major plank of his platform, although Ron Paul, who still is considered a possible candidate, did introduce a bill in Congress to decriminalize it.
Johnson's the only candidate to admit to smoking marijuana in recent years, but his drug use sounds small potatoes compared with potential rival Mitch Daniels' past:
As a student in Princeton, the Indiana governor was arrested in a police sting that netted two size-12 shoeboxes worth of marijuana, along with LSD and drug paraphernalia. Daniels was cited for pot possession but got off with a $350 fine for "maintaining a common nuisance." He told the Daily Princetonian in 1988 that because of the arrest "any goal I might have had for competing for public office were shot," and later called the incident an "unfortunate confluence of my wild oats period and America's libertine apogee"
The article doesn't mention the likely Democratic nominee, President Obama. He's admitted to smoking marijuana and using cocaine as a teen.
So in honor of the day, here's the first part of a drug "education" film they made me watch in high school starring that hip youth-culture icon, Sonny Bono. The other three parts of the film also are on Youtube. If you're not too stoned to find 'em.
