Declining a Cabinet position , Hanna secured appointment as senator from Ohio after Sherman was made Secretary of State ; he was re-elected by the Ohio General Assembly in 1898 and 1904 . After McKinley 's assassination in 1901 , Senator Hanna worked for the building of a canal in Panama , rather than elsewhere in Central America , as had previously been proposed . He died in 1904 , and is remembered for his role in McKinley 's election , thanks to savage cartoons by such illustrators as Homer Davenport , who lampooned him as McKinley 's political master
