The actress Uma Thurman, the senator-turned-college-president Robert Kerrey, and a slew of hip-hop bands are scheduled to appear tonight at a Democratic event downtown to drum up some last-minute cash to support Senator Kerry.

With the big-name celebrities, the $12,000 in expected contributions, and the hip venue, BLVD on the Bowery, you’d think the hosts would be bigwigs in the Democratic Party.

The organizers are 10th-graders who believe that America should elect the Massachusetts senator but are too young to vote in tomorrow’s election.

“We want to show America, New York, New York City, that the youth, even though they can’t be heard, still want to have a voice in our country,” one of the leaders of the youth coalition throwing tonight’s party, Wyndam Makowsky, 15, said.

Another of the advocates, Theo Brooks, who founded the group throwing tonight’s party, Outreach NYC, said his organization seeks to convince people to vote if they’re old enough and to raise money to support Mr. Kerry’s bid for the White House.

Outreach NYC plans to give the money raised at tonight’s event to Concerts for Change, a national group that supports grassroots efforts. It plans to use the proceeds to bus advocates down to Philadelphia tomorrow.

Wyndam, who attends Stuyvesant High School, Theo, who attends the Dalton School, and James Malloy, who attends the Dwight-Englewood School, launched Outreach NYC last spring, as the campaigns were heating up.

Since then, they have created a web of representatives in private, public, and parochial schools, including Brooklyn Technical High School, Brearley, Nightingale-Bamford, Horace Mann, and Fieldston. The event starts at 7 p.m. at 199 the Bowery.

The bands D-Story, Q-Unique of the Arsonists, Culture Freedom, Grand Agent, and Mr. Complex are to play until 11 p.m.
