The control and management of the Republican Party lay in the hands of Ohio Senator and Republican Party chairman Mark Hanna until McKinley's death. Roosevelt and Hanna frequently cooperated during Roosevelt's first term, but Hanna left open the possibility of a challenge to Roosevelt for the 1904 Republican nomination. Roosevelt and Ohio's other Senator, Joseph B. Foraker, forced Hanna's hand by calling for Ohio's state Republican convention to endorse Roosevelt for the 1904 nomination. Unwilling to break with the president, Hanna was forced to publicly endorse Roosevelt. Hanna and Pennsylvania Senator Matthew Quay both died in early 1904, and with the waning of Thomas Platt's power, Roosevelt faced little effective opposition for the 1904 nomination. In deference to Hanna's conservative loyalists, Roosevelt at first offered the party chairmanship to Cornelius Bliss, but he declined. Roosevelt turned to his own man, George B. Cortelyou of New York, the first Secretary of Commerce and Labor. To buttress his hold on the party's nomination, Roosevelt made it clear that anyone opposing Cortelyou would be considered to be opposing the President. The President secured his own nomination, but his preferred vice-presidential running mate, Robert R. Hitt, was not nominated. Senator Charles Warren Fairbanks of Indiana, a favorite of conservatives, gained the nomination.
