It’s become a well-worn phrase in coverage of Washington doings to refer to the “revolving door” that connects Congress and K Street — the new shorthand for DC lobbyists. The perception that the nation’s capital has degenerated into a cesspool of special interest-driven influence peddling, where lawmakers bend to the whims of high-priced lobbyists, who in turn fill their campaign coffers and ensure their electoral invincibility, is at the heart of recent polling showing Congress to be less popular than root canal, traffic jams, cockroaches, and colonoscopies.

Just how completely intertwined is Congress with the paid influence peddlers whose high-priced offices line the K Street corridor in Washington? New York Times reporter Eric Lipton offered a jaw-dropping case study in Sunday’s paper by zeroing in on Sen. Max Baucus, the powerful Montana Democrat who chairs the Senate Finance Committee.

While former members of Congress who join the lobbying world are conspicuous and invariably draw attention, the much more active revolving door involves the migration of congressional staff members into lobbying, where they can then bring clients’ issues to the attention of their former boss.  On that score, Baucus may have few rivals, Lipton reports that no fewer than 28 aides who have worked for Baucus have gone on to lobby on behalf of tax issues during the period of the Obama administration.

“K Street is literally littered with former Baucus staffers,” an executive at a wholesalers’ trade association tells Lipton. The story says former Baucus staff members have “saved their clients millions — in some cases, billions — of dollars after Mr. Baucus backed their requests to extend certain corporate tax perks, provisions that were adopted as part of the so-called fiscal cliff legislation in January.”

The story goes on to document the generous fundraising help former staffers have provided to Baucus’s campaign account. It also has all the requisite insistence from Baucus’s office (the senator himself declined to comment) that all decisions the senator makes are based on the merits of the policy, not on who is advocating them.

Ironically, yesterday’s Wall Street Journal had an op-ed co-authored by Baucus and his House Republican counterpart in which they emphasize their commitment to “writing bills in an open and transparent fashion.  No cutting deals behind closed door.”

Jonathan Chait isn’t buying it, referring instead yesterday in New York to the “Baucus industrial complex on K Street” that makes the real story behind bills moving through the Senate Finance Committee anything but transparent.

Lawrence Lessig, the Harvard law professor who was the subject of the Conversation interview in the winter issue of CommonWealth, laid out in sordid detail the path from congressional staffer to lobbyist:

Jim Cooper [a Democratic congressman from Ten­nessee] talks about Congress as a farm league for K Street, where the lobbyists work. And the image here is you’ve got these people who think of their purpose, or their objective, their business model, as, “How do I get out of Congress on my way toward becoming a lobbyist?” I think it was reinforced by a really wonderful passage in Jack Abram­off’s book, where he said the most effective technique I had was going into a Senate office, and I’d talk to the chief of staff. And I say, what are you going to do in two years? And the chief of staff says, well, I don’t know. And Jack would say, well, I want you to look me up. And Abramoff said, from that moment I owned that staffer. And not a single dollar had traded hands. What’s really disgusting is, especially at the staffer level, there’s developed a kind of awareness of who are the chumps and who are the smart people. And the chumps are the people who don’t cash out in time. And the smart people are people who’ve figured out —well, I’ve been here long enough, I’ve been on this committee, I can now cash out and have a successful career as an influence peddler. When that’s true, basically, we’ve now shifted power to the machine of lobbyists. That’s going to be great for some people. But it’s obviously not great for the way that democracy functions.

BEACON HILL

The House passes a $500 million transportation finance bill by a 97-55 margin, rejecting Gov. Deval Patrick’s push for a heftier $1.9 billion package, the Associated Press reports (via WBUR). Business leaders desert the governor. The margin fell four votes shy of the two-thirds needed to override a promised Patrick veto. CommonWealth reports that gaining passage of the bill in the Senate could be more difficult.
