Revolving-door syndrome
A high proportion of lobbyists have moved from roles as politicians, or staff members — 64% of those members of the 112th Congress who failed to get re-elected in 2012 moved into the lobbying industry. This leads to the accusation that US politics is dominated by an insider elite, whose members are able to influence the political system through the 'revolving door', which gives them constant access to those in power.
Increasingly, former members of Congress are finding their way back into the corridors of power representing the very interest groups they once regulated. This post-congressional lobbying activity has proven to be very lucrative for many ex-lawmakers. As lobbyists, former members of Congress carry significant clout that gives them access not only to their former colleagues in the U.S. House of Representatives and the U.S. Senate, but also to members of the executive branch. While generally the practice of walking through the "revolving door" has been discussed as unseemly, a bigger danger is that members of Congress might sponsor legislation that benefits their future employers.
TThe evidence in this book suggests that lawmakers who become lobbyists not only behave differently in the legislative arena than those who do not become lobbyists, but also lobby on behalf of the very interests they once regulated in Congress.
The book begins with a discussion on the intentions of the framers of the Constitution to constrain ambition. It then proceeds to show who becomes a lobbyist and how post-congressional lobbyists exploit their relationships with their former colleagues as they lobby on behalf of special interests. The book concludes by suggesting that post-congressional lobbying not only has the potential to undermine sound public policy, it also has the potential to jeopardize the legitimacy of the institution
This creates a relationship where politicians are unduly influenced, in creating public policy, by the lucrative prospect of a high-paid job for a lobbying firm when they leave politics. There are many examples of this overlap between those in politics and lobbying:
