Daley is remembered for doing much to save Chicago from the declines that other rust belt cities such as Cleveland, Buffalo, and Detroit experienced during the same period. He had a strong base of support in Chicago's Irish Catholic community and was treated by national politicians such as Lyndon B. Johnson as a pre-eminent Irish-American, with special connections to the Kennedy family. Daley played a major role in the history of the Democratic Party, especially with his support of John F. Kennedy in the presidential election of 1960 and of Hubert Humphrey in the presidential election of 1968. He would be the longest-serving mayor in Chicago history until his record was broken by his son Richard M. Daley in 2011.
