When the forces of conservatism shake the earth, Dan Rupli, Frederick's lonesome liberal, rises from his desk and goes forth from his law office to do battle.

"I'm like a 27-year cicada -- every quarter-century, I come out and do something wild," he said, getting the timing wrong, but not the sentiment. "I'm an angry man. I don't like the status quo and never did."

Unsuccessful congressional candidate, consumer advocate and inexhaustible defender of the little guy, Rupli, 61, has emerged this time to shoulder a task of near-mythic difficulty. As coordinator for the John Kerry presidential campaign in Maryland's 6th Congressional District, he aims to push this God-and-country region several percentage points to the Democrats' favor.

Rupli's office on Patrick Street, with its brass chandelier, defunct fireplace and Republican junior partner, sits near the center -- geographically, anyway -- of the sprawling district. In 2000, Al Gore lost the 6th to George W. Bush by 20 points. But those who know Rupli say that if anyone can change those numbers, he can.

"He's like a stick of dynamite, with determination and drive that's unbelievable," said Mary Tarr, who manages Kerry's Senate office and serves during her off hours as his Maryland volunteer coordinator. Though Rupli's turf covers the swath of land across the top of the state, "he's all over," Tarr said.

Just this month, Rupli has addressed audiences in Calvert, Charles, Washington, Allegany, Garrett, Kent, Montgomery and Somerset counties in Maryland, in two West Virginia counties and in Somerset, Pa., where he shouted down a Republican.

There he is on a bridge over the Potomac, on the West Virginia line, waving a Kerry for President sign, smiling when someone gestures obscenely toward him. "Another thumbs up," he likes to say.

And back in Frederick, when a newspaper declined to cover a gathering he had organized in a coffee shop, Rupli marched the Kerry supporters down the street, where they stood, chanting, outside the newspaper's office until a photographer came out.

"I think the world of him," said Frederick County State's Attorney Scott Rolle (R). Rolle challenged U.S. Rep. Roscoe G. Bartlett in this year's GOP primary, portraying himself as farther to the right than the conservative lawmaker.

"We're a funny pairing," Rolle said of himself and Rupli. But "he helped me on ground-level politics -- how to get campaign literature out, what doors to knock on."

"Our philosophies are vastly different," Rolle said. "But it just didn't matter to us. I appreciated his advice."

Rupli's underdog days began in 1969, when he joined the Justice Department's civil rights division, an office not particularly well-favored during President Richard M. Nixon's administration. Rupli would scoop up a pile of abandoned case files alleging racial discrimination, organize them by address, head south and interview plaintiffs, hoping he could gather enough information to reopen them.

In 1972, Rupli and several other lawyers left the administration.

"We'd become fed up with nonenforcement," he said. He moved with his first wife, Brenda, to bucolic Burkittsville, determined to start a quiet country law practice. Then the electric bill started going up, yet there weren't many lights on, and not much money coming in, either.

A crusade was born: against regional electric companies, fighting the fuel rate adjustment, an energy crunch surcharge that in some cases added hundreds of dollars to customers' utility bills, especially for poorly insulated homes in Appalachia. The way Rupli tells it, he called on politicians, including then-Rep. Goodloe Byron (D), hoping for help in holding the energy companies' feet to the flame.

"He wrote me a very nice letter" but did little else to help, Rupli said of Byron.

Ultimately, Rupli helped win a rate rollback, and his activism led to a run in the 1976 Democratic primary against Byron. He narrowly lost.

A favorite photo from the time shows Rupli in a freak May snowstorm in Allegany County, shaking the hand of a weary-looking factory man, snow piled from the shoulders of his suit to his earlobes.

He ran again in 1978 but "they saw me coming," and he failed again, this time by a larger margin. He served in the mid-1990s as a Maryland trade delegate to China, but for most of the years since his last congressional run, he has worked as a lawyer.

For the Kerry campaign, Rupli guides a group of volunteers -- Vietnam veterans, young mothers, minority activists, miners and college students -- whose quest to unseat Bush is about the only thing they have in common.

"At the drop of a hat, he'll drive halfway across the state to speak," said Allison de Gravelles, Kerry campaign coordinator for Anne Arundel County. She recalled a meeting in Annapolis called to ask members of the Howard Dean campaign for their help. Though many in the room were reluctant, "by the end of the meeting, all the commentary was positive," de Gravelles said. "He's persuasive [and] a good unifier.

"He's constantly thinking of new ways, new events to bring Kerry-Edwards to the people. You can watch his brain working."

For example, there is Rupli's plan for a "freedom train," an Amtrak caravan from New York to Washington, which would pick up a rainbow of clergy and activists along the way.

"Campaigns are not much higher than prison riots when it comes to organization," said Rupli, who will be a delegate to the Democratic National Convention. "But we sit between two battleground states" -- West Virginia and Pennsylvania -- "and we're going to use whatever resources we can draw out of this district to focus on them, too."

Those resources are precious: John Wiseman, a professor at Frostburg State University, is organizing student concerts and bingo games to benefit the campaign's efforts to influence voters just over the Maryland border in Pennsylvania and in the West Virginia Panhandle.

"People think of Western Maryland as one big glob, but it's not," Wiseman said. "There's an old, hard-core Democratic base" of angry people that Wiseman, with Rupli's help, is trying to energize.

Although it's a difficult challenge, trying to sway the 6th District to the Democrats, Rupli has high hopes. "Sometimes I feel a little lonely, like kind of an antique," he said. "But maybe my ideas are getting so old they'll look new."
