The 1929 New York City mayoral election was held on November 5 in concert with other municipal elections.[1] Democratic incumbent Jimmy Walker defeated Republican challenger Fiorello H. La Guardia in what was considered "a Crushing Defeat to [the] City G.O.P. [delivered]" by Tammany Hall.[2] Socialist candidate Norman Thomas also ran, as did Socialist Labor candidate Olive M. Johnson and former Police Commissioner Richard Edward Enright for the Square Deal Party.
