As The Nation documented in our recent special issue “The Gilded City,” New York today is one of the most unequal places in the country, a city where the gulf between rich and poor rivals that of Swaziland. While the Bloomberg era has transformed parts of New York into luxuriant oases of 
livability—islands of green in which bike lanes and condos flourish—vast swaths are still waiting for the good times to trickle down. Almost half the city’s population lives at or near the poverty level; in any given year, more than 105,000 New Yorkers spend at least one night in a homeless shelter, while some 1.5 million face hunger and food insecurity. Meanwhile, the public schools crumble and public housing grows mold. And though none of this is exclusive to New York—rising inequality is a nationwide affliction—it is nonetheless one of the great outrages of the last twelve years that a city government with the power to do so much more has chosen to do so little.

In running for mayor, de Blasio has promised to tackle the city’s inequality crisis head-on, harnessing what he has called “the most powerful local government on earth” to bring affordable housing, living-wage jobs, universal pre-kindergarten and genuine opportunity to the city’s millions of forgotten residents. “My job is to help New Yorkers live in New York,” he told New York magazine in a recent interview. The words sound nice, but what makes them compelling is the fact that de Blasio has backed them up with a platform that The New York Times has described as “the meatiest material presented by any candidate to date.”

There is a lot to like, in proposals that range from education and homelessness to public safety—but among the ideas that we found most persuasive is his unusually diverse economic development strategy, which embraces not only job creation but also enhanced labor protections and long-overdue investments in New York’s once-great public universities. De Blasio was a major force behind living-wage and paid-sick-leave legislation—indeed, he fought for much stronger bills than those ultimately passed by the City Council—and his platform contains additional policies to increase wages for the city’s working poor. He is also steadfastly pro-union, which is both a welcome change and a crucial one after twelve years of an administration so hostile to labor that all 152 of the city’s public unions are without contracts. And in an effort to stanch New York’s affordable-housing crisis, he has put forward an ambitious plan to build or preserve nearly 200,000 affordable-housing units over the coming decade, while pledging to remove wasteful tax breaks for real estate developers.

Perhaps most unexpected is the centerpiece of de Blasio’s platform: a city income-tax surcharge on New Yorkers earning over $500,000 a year to provide truly universal, full-day pre-kindergarten to every child in New York City—a game-changing investment in the next generation of New Yorkers. The revenue from this surcharge would also fund after-school academics, athletics and cultural programming for every middle-schooler. It is notable that de Blasio made this tax proposal in the belly of the beast, at a meeting of the city’s corporate leaders.

Finally, de Blasio has been one of the fiercest critics of the NYPD’s stop-and-frisk policy, the racially discriminatory police practice that has subjected hundreds of thousands of black and Latino men to illegal searches and violated their constitutional rights, according to a blistering federal court ruling handed down on August 12. And of the candidates, he has been the most vocal and persistent supporter of a bill to prohibit racial profiling and impose greater police oversight. He has also pledged to replace Police Commissioner Ray Kelly, who continues to stubbornly defend stop-and-frisk.

In taking strong stands on these and other important issues, de Blasio has injected a valuable dose of substance into the election and earned our support.

Other candidates have also advanced strong ideas. Former comptroller and 2009 mayoral candidate Bill Thompson, for example, deserves credit for proposing measures to fight what he calls the city’s “growing, climbing, pervasive, insidious poverty,” including giving homeless families priority for Section 8 housing and supporting paid sick days for the many workers who don’t have them. And we welcome his solid proposals to fund the MTA’s capital programs (a theme that Sal Albanese has extended in an impressive set of proposals to improve transportation and street safety). But these ideas often feel more like well-meaning tweaks than the far-reaching measures required for change. Moreover, Thompson’s confusing stance on stop-and-frisk and police oversight—he has strongly condemned racial profiling but refused to support City Council bills to rein it in—raises questions about how vigorously he would fight for sorely needed reforms.

Comptroller John Liu, for his part, has run an unabashedly progressive campaign that has not shied away from taking on some of the most contentious issues of the last few years. For instance, he has unequivocally condemned not only the NYPD’s stop-and-frisk policy but also its surveillance of Muslim New Yorkers—a position that we strongly urge other candidates, including de Blasio, to adopt. Yet the allegations of fundraising improprieties within his campaign have tarnished his candidacy in ways we can’t overlook.

City Council Speaker Christine Quinn has also presented some useful ideas and impressed us with her willingness to engage in hand-to-hand combat with the Bloomberg administration on certain issues, such as the city’s harmful homelessness policies. But as speaker, she has all too often used her power to protect corporate and real estate interests and to block measures intended as a progressive counterweight to the Bloomberg agenda. Most egregiously, she refused for more than two years to allow a vote on paid-sick-leave legislation. And, of course, she played a central role in overturning term limits in 2008, thus helping Bloomberg—and herself—to four more years in office. New Yorkers had already voted twice in favor of term limits, and they deserved better. They deserved politicians who would honor their explicitly stated will.

Which brings us back to de Blasio.

Throughout the last twelve years, many of New York’s hardest-hit communities have responded to the struggles and inequities of the Bloomberg era with smart ideas and savvy campaigns. As much as this has been a time of frustration, it has also been a time of grassroots creativity and hope. Now we have a mayoral candidate who has vowed to bring some of these ideas to City Hall—and if he can harness a broad coalition of progressive forces (and if just a few of the right stars align), he can win. Indeed, as we write this endorsement, de Blasio’s campaign is gaining momentum.

No doubt there will be tremendous challenges should 
de Blasio become mayor. New York is a fractured and fractious city, and he would almost certainly face strong headwinds from a number of quarters, the city’s powerful Wall Street and real estate interests among them. Yet with the help of a newly minted City Council—one that is expected to emerge from this year’s election a more progressive body thanks to the efforts of groups like the Progressive Caucus—a Mayor de Blasio might have a real chance to begin stitching the city’s tattered social contract back together. And for the first time in a long time, New York might become a national model not of flagrant inequality, but of forward-thinking efforts to create true opportunity for all its residents.

“New York City is also an idea,” de Blasio has said, echoing this notion. “It’s a culture and a history. We are the keepers of the flame of inclusion and tolerance and diversity.”

In the service of that idea, we endorse Bill de Blasio for mayor.
