Answer:
"Roosevelt returned from war as a hero, and regained elective office, now as Governor of New York, then the nation's largest, most populous state. While Governor, Roosevelt worked again to end corruption and to develop the state's civil service. Roosevelt ran with McKinley within the latter man's reelection campaign, and won.
The odore Roosevelt promised to continue McKinley's program, and initially he worked closely with McKinley's men. His 20,000-word address to the Congress in December 1901, asked Congress to curb the facility of trusts ""within reasonable limits."" They didn't act but Roosevelt did, issuing 44 lawsuits against major corporations; he was called the ""trust-buster." "Mark Hanna was the rival power within the Republican Party . Hanna died, and Roosevelt had an easy renomination and reelection in 1904. He won 336 of 476 electoral votes,
and 56.4% of the total popular vote. He therefore became the primary President who came into office due to the death of his predecessor to be elected in his own right."
