In his new book, Man of Iron,\xa0author Troy Senik discusses Cleveland\u2019s improbable rise from obscure lawyer in upstate New York to mayor of Buffalo, governor of New York, and finally, in 1885, president of the United States; followed by his subsequent loss of the White House in the election of 1888 to Benjamin Harrison, and his unprecedented\u2014and as yet unrepeated\u2014return to the Oval Office after beating Harrison in 1892.
