Definition
Fiorello LaGuardia was the reformist Republican-Fusion mayor of New York City from 1934 to 1945, and the fulcrum of Robert Moses's middle career. A short, fiery, multilingual former congressman, he broke Tammany Hall's grip on City Hall and tied his administration to a vast public-works program.
LaGuardia gave Moses the parks portfolio, the city's federal-funding pipeline, and political cover; in return, Moses gave him visible, photographable accomplishments — playgrounds, pools, parkways — at a speed no other administrator could match.
Why it matters
How it works
A reform mayor in a machine city needs two things: a clean public face and a delivery machine that can outproduce the patronage networks he is displacing. LaGuardia supplied the first; Moses, with his federal money and authority structures, supplied the second. When the two clashed — over personalities, over credit, over Moses's tactics — LaGuardia almost always blinked, because firing Moses would have collapsed the construction tempo that justified his administration.
The pattern recurs in urban politics. Reformers who promise more than punishment must find a builder whose energy can be harnessed without being fully controlled.
