The right to petition Congress for the redress of grievance is enshrined in the Constitution, but those who earn their living by exercising that right on behalf of others — lobbyists — are being increasingly vilified.
Democratic presidential candidate Barack Obama has made a campaign issue of the “undue influence” of lobbyists in Washington, the implication being that they also have too much influence on rivals like Sen. Hillary Clinton.
John Edwards boasts the he have never taken a contribution from a lobbyist and called on the other candidates to do likewise.
