It seems to me the issues of drunk driving and drinking age are orthogonal. There were just as many kids driving drunk (under 21) when I was in HS as there were driving drunk (over 21) when I was in college. Age had nothing to do with it, and legal access to alcohol didn't either. MADD's argument is fallacious, but it's the same line of reasoning that those advocating banning of firearms take. Somehow making guns illegal will cut down on gun-related-deaths. Nevermind that the people that tend to shoot other people don't really care if they have to get a gun illegally, just like kids that drink underage don't really care that they are getting alcohol illegally. In a perfect world, you could just remove all guns at once and perfectly enforce the alcohol age limit every time (and there would be no black market), but that isn't reality. If MADD was really interested in cutting down on drunk driving, they'd campaign for stiffer penalties and education. And, like someone else here pointed out, they'd campaign for public transportation. When the car is the only option to get home, your choices are either "don't drink" or "drive drunk."
