Hobart's death left MCKINLEY without a running mate in the elections of 1900. The party chose New York Governor TEDDY ROOSEVELT, a reluctant candidate who was pushed into the position by party insiders -- some say in an effort to get him out of New York. Roosevelt spent his time as vice president building up his ambition to run for president in the 1904 election. But fate intervened, in the form of Leon Czolgosz, who walked up to President McKinley on September 6, 1901 and shot him. McKinley died eight days later and Roosevelt was sworn in as president on September 14, 1901.
