A Duty Not To Vote?

Let me be politically incorrect and say that maybe some people shouldn't vote.

I know I'm swimming against the tide. Get-out the-vote groups now register young people at rock concerts. HeadCount cofounder Andy Bernstein told me: "We registered over a 100,000 people. It is so imperative that this generation's voice is heard."

But wait. Is that really a good idea? Many kids don't know much. At a HeadCount concert, "20/20" asked some future voters, "How many senators are there?" One said 12, another 16, and another 64. One girl guessed, "50 per state."

Should we have a litmus test for voters? John Stossel doesn't think so - yet.
