MSNBC's Lawrence O'Donnell declared former Sen. Scott Brown's political career officially deceased during his Rewrite segment that Monday evening now that Brown had decided to give it the kiss of death and take a job as a lobbyist:

Scott Brown officially ended his political career on Monday. Instead of choosing to serve in public office, Scott Brown has decided to take a job at a Boston law firm, Nixon Peabody, according to The Boston Globe’s report. The law firms states that Brown “will focus his practice on business and governmental affairs.” But as MSNBC’s Lawrence O’Donnell states, “That is the lobbying world’s euphemism for lobbying ‘government affairs.’ So today, Scott Brown became a lobbyist. That is death for a politician every hoping to run for office again, and even Scott Brown is smart enough to know that.” [...]

Last month, Scott Brown signed on as a Fox News contributor. When Sarah Palin quit the Alaska governorship and left state affairs to Alaska Lieutenant Governor Parnell, she signed a contract with Fox News. So today, “[Brown] competed a full Palin by quitting politics completely and simply chasing the money that his political celebrity has earned him.”

O’Donnell continued to compare the two politicians’ trajectories. “Scott Brown is smart enough to know that he cannot go off and become a lobbyist and then take that dreaded occupation on to a debate stage as a candidate for anything ever again. This is Scott Brown’s full Palin—take FOX News’s money and then go for the money anywhere else he can. Like Sarah Palin, Scott Brown is all about the money, now.”

Here's more from Think Progress on Brown's new job: After Watering Down Financial Reform, Ex-Senator Scott Brown Joins Goldman Sachs’ Lobbying Firm:

During his nearly three years in the U.S. Senate, Scott Brown (R-MA) frequently came to the aid of the financial sector — watering down the Dodd-Frank bill and working to weaken it after its passage — and accepted hundreds of thousands of dollars in campaign cash from the industry. Now, the man Forbes Magazine called one of “Wall Street’s Favorite Congressmen” will use those connections as counsel for Nixon Peabody, an international law and lobbying firm.

The Boston Globe noted Monday that while Brown himself will not be a lobbyist — Senators may not lobby their former colleagues for the first two years after leaving office, under the Honest Leadership and Open Government Act of 2007 — “he will be leaning heavily on his Washington contacts to drum up business for the firm.” The position will also allow him “to begin cashing in on his contacts with the financial services industry, which he helped oversee in the Senate.”

Among the lobbying clients represented by Nixon Peabody is Goldman Sachs, the Wall Street behemoth that reportedly skirted the Dodd-Frank rules . Brown received $10,000 in PAC contributions from Goldman and more than $100,000 in contributions from its employees.
