A lawyer in Buffalo, N.Y., he became (1882) the "veto mayor" who drove corruption from the city administration. He won the attention of Daniel Manning and the reform Democrats and was elected governor of New York. Cleveland further built his reputation as an enemy of machine politics by breaking violently with the Tammany leader, John Kelly, and supporting the bills prepared by Theodore Roosevelt to improve the government of New York City.
