Chris Hughes, the 24-year-old Facebook co-founder and multimedia guru for the Obama campaign, visited Drexel University last week to urge students to register to vote before Pennsylvania's March 24th deadline - preferably through his website. With most schools on or about to go on Spring Break, the push to get young people registered in the Keystone state is particularly urgent. Through its Drexel Votes 2008 program, the University has already registered more than 1,000 new voters this year.
