The Bronx has often shown striking differences from other boroughs in elections for Mayor. The only Republican to carry the Bronx since 1914 was <answer>Fiorello La Guardia</answer> in 1933, 1937 and 1941 (and in the latter two elections, only because his 30-32% vote on the American Labor Party line was added to 22-23% as a Republican). The Bronx was thus the only borough not carried by the successful Republican re-election campaigns of Mayors Rudolph Giuliani in 1997 and Michael Bloomberg in 2005. The anti-war Socialist campaign of Morris Hillquit in the 1917 mayoral election won over 31% of the Bronx's vote, putting him second and well ahead of the 20% won by the incumbent pro-war Fusion Mayor John P. Mitchel, who came in second (ahead of Hillquit) everywhere else and outpolled Hillquit city-wide by 23.2% to 21.7%.
