The Next President of the United States

Two military school cadets, one a junior and the other a senior, compete in an important competition before the entire academy. When the junior cadet wins, the senior cadet attacks him.
Their paths cross frequently as they pursue separate careers—the junior as a university professor and author, the senior as a corrupt lobbyist, and eventually, a member of Congress.
Years later, hearing that he is about to announce his candidacy for President, his rival unearths the secrets of the Congressman's immoral and illegal past, including his involvement in a mysterious death, and recruits hi-tech accomplices to sabotage the press conference.
