Slog tipper Kevin sent along the news that Herman Cain, who doesn't often make sense, makes a little bit of sense on medical marijuana:

At a campaign stop in Urbandale, Iowa, Tuesday, Republican presidential candidate Herman Cain said he supports letting states establish their own laws regarding medical marijuana.
"If states want to legalize medical marijuana, I think that's a state's right," Cain said, according to NBC News.

I guess if you babble on long enough, sometimes something that makes sense pops out.
