After finishing college, Haddad began a career moving back and forth between business, journalism, and politics. He first worked for Senator
Estes Kefauver from 1954 to 1956 and helped secure his nomination as
Adlai Stevenson’s vice-presidential running mate, beating out
John F. Kennedy at the
1956 Democratic National Convention. He later worked for the
New York Post and helped expose the corruption of
Robert Moses, which led to his eventual downfall. After the Peace Corps, Haddad returned to work for the
New York Herald Tribune, whose publisher,
John Hay Whitney, was his father-in-law. After losing the primary, he was the inspector general for the
Office of Economic Opportunity from 1964 to 1966. In his business career, Haddad joined a venture with
John DeLorean in the newly founded
DeLorean Motor Company in 1979 and was its marketing director. He left the company and published a book,
Hard Driving: My Years With John DeLorean, chronicling the rise and fall of their joint venture. He was
Mario Cuomo's campaign manager in the
1982 New York gubernatorial election. Afterwards, he began to lobby to reduce the
prices of prescription drugs and was the chairman of the Generic Pharmaceutical Industry Association that was merged into the
Association for Accessible Medicines. His lobbying was instrumental in the passing of the
Drug Price Competition and Patent Term Restoration Act (Hatch-Waxman Act) in 1984, which helped launch the
generic drug industry in the United States. == Personal life ==
