So far, the big-name musicians who’ve endorsed presidential candidates have appealed mainly to grownups.

Mainstream rockers like Bruce Springsteen and Jon Bon Jovi have come out for Kerry, while slick country stars such as Billy Ray Cyrus and the Gatlin Brothers are boosting Bush. But according to Fat Mike of the band NOFX, the teeming masses of teens who follow the skate-punk world are “98 percent against Bush.”

Of the 300 bands who take part in the popular Vans Warped Tour, now celebrating its 10th summer as the definitive skate-punk festival, Mike claims the sole “out” Republican is Joe Escalante, the leader of the Vandals, “80s punk veterans.

“He’s a good guy,” Mike says, “but he’s a lonely one.”

Recognizing the untapped power of the Warped kids inspired Mike to start PunkVoter.com just four months after the 2000 election. But only this summer has his movement been able to prove its power on the charts.

In May, the organization’s first compilation CD, “Rock Against Bush, Vol. 1,” debuted at No. 54 on Billboard’s Top 200 album chart. That’s higher than any of NOFX’s albums.

Boasting tattooed bands like Good Charlotte, Pennywise and Sum 41, the CD became the nation’s No. 1 indie record, hit No. 2 in Internet sales and was the No. 1 most-added entry at college radio.

SoundScan pegs its sales at 110,000 so far, though organizers claim it has moved nearly 300,000, with the balance sold at mom-and-pop stores, which aren’t included in SoundScan’s figures.

Tuesday, the series’ second volume hit the charts. It should do even better than the first, considering that it includes unreleased tracks from bigger names like No Doubt, Green Day and the Foo Fighters.

Fat Mike says the more popular acts wanted to participate the first time, but “bigger bands are flakier. They take longer to get the songs to us.”

At the Warped shows, there’s no shortage of political pamphlets from PunkVoter.com. But Mike claims the group doesn’t directly endorse a candidate: “We just say things like, “If you want abortion to be made illegal, Bush is your man.”‘

The singer says he hopes the movement has a secondary effect – to counter the view of skate-punks as jokey slackers.

“We do like getting wasted,” he assures. “But then you have a band like Bad Religion, where the singer has a doctorate.”

Mike acknowledges that many in the Warped audience can’t take full advantage of his movement’s message. They’re too young to vote, with roughly one-third under 18.

“They can still give the material to their older brothers or their parents,” Mike offers.

And, as Whitney Houston might say, even skate-punk children are the future.
