When John Lawrence took over the top Democratic staff job in the House of Representatives, chief of staff to Minority Leader Nancy Pelosi (D-Calif.), Republican strategists may have been disappointed.

A 31-year veteran of the House, the low-key, cerebral Lawrence is unlikely to produce the eyebrow-raising headlines that top Republican staffers have (see Tim Berry’s lavish trip to the Super Bowl, Tony Rudy’s golf outings or Dave Hebert’s tumultuous reign in the whip’s office). He is by his own description a policy guy, a wonky Ph.D. in American history who brings the experience of mark-ups and conference committees to the leader’s office.

And as the longtime top aide to Rep. George Miller (D-Calif.), a lawmaker so attuned to Pelosi that he has been called her alter ego, Lawrence, 56, has been one of the closest staffers to the leader’s office never to have actually worked there.

He is not expected to take the operation in a direction radically different from his predecessor, George Crawford, who left earlier this summer to return to California.

“I wasn’t brought here to shake up or redesign what has been a very successful role that the leader is playing and that her staff is playing,” he noted recently. “I think I was brought here to bring my expertise and contribute to it, but not to reinvent it.”

But people do have high expectations for the soft-spoken Lawrence. Known for decades as “Miller’s guy,” he is bright, articulate and dogged, but at times can be laid back and mischievously droll, colleagues say. Behind an often-placid façade, Lawrence shares the Democratic dreams of attaining a battle of Aqaba, in which Democrats will come out of the desert and win back the House.

Lawrence turned fiery when talking about House Republicans.

“When I came here … you didn’t have a systematic effort to disenfranchise half of the American electorate,” he fumed. “That’s an abuse of the process. We’re supposed to debate difficult issues here. … Today you have one or two amendments on key legislation and the votes are kept open for hours until they turn the way they like.”

All that, cumulatively, will cause voters to reassess whom they put in Congress, he argued. Is a coup possible in 2006? “Of course!” he replied. In politics, nothing is written.

Lawrence’s colleagues say he might make modest changes to the leader’s operation, but no major modifications loom on the immediate horizon.

“I think he’ll be more active than George [Crawford], more engaged,” said one senior Democratic aide. “George tended more to let things move along and inject himself from time to time. John is more aggressive.”

Unlike Crawford, who showed a mastery of House procedures and rules, Lawrence’s expertise lies in specific policy areas, having worked as the top Democratic staffer on the Education and Workforce Committee from 2000 to this year and the Resources Committee from 1993 to 2000. His most recent legislative work focused on the Conservation and Reinvestment Act of 2000 and the No Child Left Behind Act of 2002. From 2003 until he took up his current post July 11 he also served as a top aide to the Democratic Steering and Policy Committee, a principal decisionmaking panel for the House Democratic caucus and one in which Pelosi and Miller work together closely crafting legislation and coordinating messages.

Before accepting the offer from Pelosi, Lawrence had worked for Miller since his first congressional campaign in 1974 in something of a symbiotic collaboration, which spanned three decades.

“They’re a perfect team,” said Phil Schiliro, a longtime aide to Rep. Henry Waxman (D-Calif.). “They seem completely in sync. They share the same policy goals and work seamlessly.”

Asked about his relationship with Miller, Lawrence paused and then chose his words carefully.

“That’s an interesting question,” he said at last. “We’ve had a very good working relationship. … Over time it became a hand-in-glove operation. We sometimes referred to it as a ‘professional marriage’. We’d finish each other’s sentences, eat off each other’s plates, our families know each other. Thirty years is lots more than most marriages.”

It’s a working relationship both Lawrence and Miller know they will miss.

“We’re like brothers,” Miller said. “We have shared so many experiences, legislatives victories, births of children and grandchildren, all of that together. [But] we look at one another now and both think this is the way it should be.”

Lawrence was raised in a suburb of New York.

“I’m from Paterson, N.J. Would you like to hear more about Paterson?” he asks hopefully, revealing a wry wit. Paterson was founded by Alexander Hamilton and was promoted as the first industrial city in the U.S. — interesting!

His father, a doctor, was the son of Czechoslovakian immigrants. His mother, a nurse, came from Poland in 1938 just as it became clear that Jews should flee the country if they could. Her parents did not and perished in the Holocaust.

Lawrence graduated from Oberlin College and received his doctorate from the University of California at Berkeley. He has two sons — Samuel, 15, and Elijah, 9 — with his wife, Deborah Phillips, who chairs the psychology department at Georgetown University.  As one might expect, both attend public schools in the District of Columbia.

Lawrence won’t have much free time in his new job, but if he did he would most likely spend it playing the guitar, a lifelong hobby. He sings folk music, often composing his own songs in a style reminiscent of James Taylor. He has recorded two CDs and even performed a few times, most notably at Barnes & Noble in Bethesda, to the delight of colleagues.

A song called “Dung Beetle” has been a best seller for him, but when asked for one of his best lyrics, he volunteers a lullaby he sings to his younger son at night: “The sun is setting and the moon will soon arise/ You’ll see tomorrow dawning through your dreamland eyes.”
