The second-day story from New York City’s primaries last week could have been the exceptional performance of the city’s unique system of small-donor public financing. By providing a six-dollar public match for every dollar raised in contributions of $175 or less, the system enabled the little-known Scott Stringer to compete with and defeat Eliot Spitzer’s family fortune in the race for Comptroller. On the Republican side, it helped mayoral nominee Joe Lhota, who received almost half his total spending in public money, to overcome another self-financed millionaire. The top three Democratic candidates for mayor finished in reverse order of the amount of private money they had raised, and as Alec MacGillis noted here, public financing allowed the eventual nominee, Bill de Blasio, to resist the policy preferences of big donors, such as opposition to paid sick leave. Dozens of city council and other races featured three or more candidates with enough money to compete. But instead of celebrating a system that finally emerged from the shadows of Michael Bloomberg’s personal spending to show its value, we’ve had handwringing about the rise of “outside money,” or spending by groups other than the candidates and parties, in New York City politics. Jim Dwyer in The New York Times argued that outside spending was “reshaping” city politics, focusing on three independent committees: one that promoted “Anybody But [Christine] Quinn,” based on the City Council speaker’s refusal to block horse carriages from Central Park; a tiny committee formed to support Lhota, with contributions solely from David and Julia Koch; and Jobs for New York, the biggest outside spender, a front for the real estate industry.
