An hour and a half later, those inside could be forgiven for wondering the same thing. While they waited for the show–officially slated to run from noon to 2 p.m.–the teens and twentysomethings bopped away to some MTV favorites. They mimicked N’Sync’s choreographed concert dance moves as the group’s megahit “Bye Bye” played over the sound system. Then they listened to Rage Against the Machine’s anti-capitalist anthem “Sleep Now In the Fire” as Michael Moore’s video played on screen above the bar. Reporters and camera crews casting about for something, anything, to do resorted to interviewing Wilmer Valderrama, a star of Fox’s “That ’70s Show.”

It wasn’t until 1:45 that the show began. Following two songs from Kina and some MTV chatter, Kristin and Karenna finally took to the stage, urging young voters to get involved in the campaign and stumping for their father. “I can assure you that he gets an earful” on issues important to young people, 23-year-old Kristin told the audience of several hundred. She also announced that, like Bill Clinton before him, the vice president has agreed to hold a town meeting with the cable music channel on September 26.

Next came Karenna. “We gotta roll up our sleeves and get out there and get involved and resist that ironic detachment,” the 27-year-old urged in a slow, measured manner reminiscent of her father’s. Then the Gore daughters, joined by 21-year-old sister Sarah, sat down and helped register the young crowd while TV cameras rolled and photographers angled for the best view. With 33 new voters signed up, their MTV mission accomplished, the Gore sisters hopped back in their Secret Service minivans and drove off down Sunset Boulevard.
