K Street and the health-care sector spent bucketloads of money to try to elect Martha Coakley in 2010, thus trying to keep Scott Brown out of the Senate (because they wanted to pass Obamacare). But this experience didn’t give birth to any populism in Brown, apparently, as he quickly became one of the favorite Republicans of Wall Street.

In his 2012 re-election, Brown was the leading congressional recipient of Wall Street money, in part because he was running against Wall Street scourge Elizabeth Warren. Brown successfully watered down Pat Toomey’s effort to deregulate finance in a way that would threaten financial service giants like Fidelity.

So, despite K Street’s hostility to Brown in 2009, nobody’s really surprised that Brown has joined the financial-services practice of a lobbying firm:

Former U.S. Senator Scott Brown has joined international law firm Nixon Peabody LLP as counsel in the firm’s Boston office. Given his background in public service at both the national and state levels, Brown will focus his practice on business and governmental affairs as they relate to the financial services industry as well as on commercial real estate matters.

Nixon-Peabody’s clients include Goldman Sachs and Sallie Mae.
