That seems to be the take of Times magazine:

Politics might be rock ‘n’ roll for nerds, but the nerds aren’t supposed to be quite this nerdy. The leader of the disaffected in next year’s presidential election – the Howard Dean, the Ross Perot, the Pat Buchanan – is a kindly great-grandfather and obstetrician whose passion is monetary policy. Paul, a 72-year-old hard-core libertarian Republican Congressman who is against foreign intervention, subsidies and the federal income tax, is not only drawing impressive crowds (more than 2,000 at a post-debate rally at the University of Michigan last month) but also raising tons of cash. In the third quarter of 2007, Paul took in $5.3 million (just slightly less than G.O.P. rival John McCain), mostly in small, individual donations. On Oct. 22, he aired his first TV ads, $1.1 million worth in New Hampshire.
The numbers are even more impressive considering that as of early October, 72% of G.O.P. voters told Gallup pollsters they didn’t know enough about Paul to form an opinion. He has been able to attract followers in the debates, where he’s presented a clear, simple philosophy of personal freedom and responsibility. He bluntly refers to the U.S. as an empire. And the nerdiness lends Paul’s simple message an aura of credibility, especially on a stage with more polished politicians and their nuanced positions. “He’s about something that American nerd culture can get on board with: really knowing one subject and going all out on it,” says Ben Darrington, a Ron Paul supporter at Yale. “For some people, it’s Star Wars. For some people, it’s Japanese cartoons. For Ron Paul, it’s free-market commodity money.”
The libertarian’s traction is most apparent on the Internet, where his presence far outstrips that of any candidate from either party. His name is the most searched, his YouTube videos the most watched, his campaign the topic of songs by at least 14 bands. “The last thing I would listen to is rap,” Paul says. “But there’s something going on when there’s a rap song about the Fed.” On Tuesday, both Paul and Tom Cruise were guests on the Tonight Show with Jay Leno. The actor went to Paul’s dressing room to thank him for his work on a bill fighting the forced mental screening of grade-school kids. “Go. Go. Go. Go hard,” Cruise said. Paul turned to an aide and asked, “What movies has he been in?”

And then there’s this:

At the Iowa State event, a student stood outside in a tricornered hat and Revolutionary War”era suit, ringing a bell. Representative Tom Tancredo, another long-shot G.O.P. candidate, tells me that after a debate in New Hampshire, one of his staffers walked up to a guy in a shark costume and asked him if he was a Ron Paul supporter. “No. They’re all nuts,” replied the shark. “I’m just a guy in a shark suit.” There is a subset of Paul supporters who believe 9/11 was an inside job by the U.S. government. And there are anarchists as well: They’ve picked Nov. 5, Guy Fawkes Day, for a fund-raising drive.

One good thing about Ron Paul’s run, he makes the race more interesting. Though, I wish he was making the Democrat’s race more interesting.
