Explain the factors that led to kennedy's victory over nixon

Fraud from the Chicago "river vote" gave Kennedy the State of Illinois and the electoral college victory.

"Kennedy won Illinois by less than 9,000 votes out of 4.75 million cast, or a margin of two-tenths of one percent. [16] However, Nixon carried 92 of the state's 101 counties, and Kennedy's victory in Illinois came from the city of Chicago, where Mayor Richard J. Daley held back much of Chicago's vote until the late morning hours of November 9. The efforts of Daley and the powerful Chicago Democratic organization gave Kennedy an extraordinary Cook County victory margin of 450,000 votes—more than 10% of Chicago's 1960 population of 3.55 million—thus barely overcoming the heavy Republican vote in the rest of Illinois. Earl Mazo, a reporter for the pro-Nixon New York Herald Tribune, investigated the voting in Chicago and claimed to have discovered sufficient evidence of vote fraud to prove that the state was stolen for Kennedy.
