La Guardia, a Republican who appealed across party lines, was very popular in New York during the 1930s. As a New Dealer, he supported President Franklin D. Roosevelt, a Democrat, and in turn Roosevelt heavily funded the city and cut off patronage for La Guardia's enemies. La Guardia revitalized New York City and restored public faith in City Hall. He unified the transit system, directed the building of low-cost public housing, public playgrounds, and parks, constructed airports, reorganized the police force, defeated the powerful Tammany Hall political machine, and reestablished employment on merit in place of patronage jobs. La Guardia is also remembered for his WNYC radio program "Talk to the People," which aired from December 1941 till December 1945.
