I saw Abbie Hoffman (Steal This Book) speak at my college years ago and even though he was a liberal, he spoke an awful lot of sense on some topics. He said that if people from 18 to 21 didn't become informed and start voting, they were going to lose the right. He said that it was obvious that they didn't vote because if they did, they'd be able to drink.
Just as an aside, he also said that you should always try to get your news from multiple sources so that you get the true story.
No suprise Hoffman had some good ideas.
Classic Liberals are what we call "conservatives" today.
