The strength and prestige of the American presidency has waxed and waned since George Washington. Accidental Presidents looks at eight men who came to the office without being elected to it. It demonstrates how the character of the man in that powerful seat affects the nation and world. Eight men have succeeded to the presidency when the incumbent died in office. In one way or another they vastly changed our history. Only Theodore Roosevelt would have been elected in his own right. Only TR, Truman, Coolidge, and LBJ were re-elected.
