A story in the New York Times covers the disenchantment young people are experiencing this election verses their enthusiasm for politics in 2008. Twenty-year-old Maria Verdugo, a recent college graduate, describes her sweeping memory of the last time we elected a president: "[S]omething about Obama saying we needed a change."
Something like that.
Also in the story, this:
“The concern for Obama, and the opportunity for Romney, is in the 18- to 24-year-olds who don’t have the historical or direct connection to the campaign or the movement of four years ago,” said John Della Volpe, director of polling at the Harvard Institute of Politics. “We’re also seeing that these younger members of this generation are beginning to show some more conservative traits. It doesn’t mean they are Republican. It means Republicans have an opportunity.”
