WASHINGTON -- Young Americans aren't just less likely to vote than their older compatriots. They're also less likely to believe that everyone should cast a ballot, according to a new HuffPost/YouGov poll. Most Americans age 45 and over say everyone should vote, according to the survey. But people under 30 are more than twice as likely to say that only the well-informed should cast a ballot as they are to say that all eligible citizens should do so. "The results don't startle me," said Peter Levine, director of Tufts University's Center for Information and Research on Civic Learning and Engagement.
