Jack Abramoff had just delivered a primer on the corruption of Congress when a University of San Francisco graduate student in public affairs posed the question: Does ethical lobbying exist, or is the cutting of moral corners just part of the job description? Abramoff, whose mastery of capital sleaze earned him a fortune and then a prison term, estimated that 95 percent of the thousands of lobbyists who populate Washington are ethical. He was, by his own admission, among the 5 percent. The problem is, when you're one of those (unethical) lobbyists, you will be able to crush the other lobbyists," said Abramoff, now 55, repentant after 43 months in federal prison and on a crusade to reform the system he exploited so adroitly. Abramoff's reform plan ... would expand the definition of lobbyist to anyone (person or corporation) that tries to influence legislation, impose a limit on campaign contributions to $500 per election cycle and prohibit legislators, staffers and administration decisionmakers from lobbying activity for 10 years after leaving government. In Abramoff's eyes, well-directed money is the only way to overcome the corrosive influence of strategically distributed money in Washington. He has written a book, Capitol Punishment: The Hard Truth About Washington Corruption From America's Most Notorious Lobbyist, and become an advocate of political reform. He still owes nearly $44 million in restitution for defrauding his tribal clients.
