Nicknamed "Deanie-babies," they are the campaign's computer-savvy teens and twenty-somethings - many who've left college and even jobs - driven to beat President Bush.
Inspired by Dean's opposition to the Iraq war, 19-year-old Sam Simon joined the movement.
"There's a feeling among young people that this is the great movement of our time," Simon told CBS News Correspondent Jim Acosta.
On the day the bombs started falling in Baghdad, Simon dropped his own bombshell on his parents – he withdrew from Harvard University.
"I think she [Simon's Mother] had a moment of pure terror when I first said it," Simon said.
College student Michael Whitney launched a "students for Dean" website that's attracted thousands of supporters and has been adopted by the campaign.
"It's really refreshing to see that this is working and that people can make a difference," Whitney told Acosta. "It's not just about the millionaires. It's not just about the most powerful people in government. It's good to see."
While these legions of youthful supporters have made Howard Dean hip, some political observers question whether the campaign is taking on an old anti-war image that's doomed Democrats in the past.
"I don't think you can count on running a presidential campaign on the twenty-something set," presidential historian Douglas Brinkley said.
Some in the party are having flashbacks to 1968, Acosta reports, when students flocked to Vietnam war critic Eugene McCarthy - who forced Lyndon Johnson out of the race - but lost the nomination.
George McGovern rallied young Americans against the war in '72 and was trounced by Richard Nixon.
"You know, pop hits come and go," Brinkley said. "It's your favorite song for a month and then you're on to something else. Certainly, Howard Dean's been the college pop hit."
But Simon disagrees with such sentiment.
"It's a different time. It's certainly a different campaign," he said.
Too young to remember Vietnam, Sam Simon and the "Deanie-babies" insist their campaign is about the future – and how they plan to change it.
