NEW YORK -- Bill de Blasio held a clear lead Tuesday night in New York City's mayoral Democratic primary as polls closed, according to early and incomplete voting returns. It was unclear, though, whether he would top the 40 percent threshold needed to avoid a runoff.
Mr. de Blasio's rise was as sudden as it was unexpected. Not even two months ago, he was an afterthought in the campaign. But he surged in part thanks to an ad blitz that centered on his interracial family, his headline-grabbing arrest while protesting the possible closure of a Brooklyn hospital and the defection of ex-congressman Anthony Weiner's former supporters in the wake of another sexting scandal.
With 45 percent of precincts reporting, Mr. de Blasio, the city's public advocate, has about 39 percent of the total vote. Former city Comptroller Bill Thompson has 26 percent, and City Council Speaker Christine Quinn has 15 percent. They were followed by current city Comptroller John Liu at 8 percent and Mr. Weiner at 5 percent.
Exit polling showed the appeal of Mr. de Blasio to be broad-based: He was ahead in all five boroughs; was ahead of Mr. Thompson, the only African-American candidate, with black voters and ahead of Ms. Quinn, the lone woman in the race, with female voters. He also led Ms. Quinn, who is openly gay, among gay voters. The voter interviews were conducted by Edison Media Research for The Associated Press and other news organizations.
But if no candidate surpasses 40 percent of the vote, the top two finishers advance to an Oct. 1 runoff.
The winner of that contest would face the Republican nominee in the Nov. 5 general election. Joe Lhota, ex-MTA chairman and former deputy mayor to Rudolph Giuliani, was battling billionaire grocery magnate John Catsimatidis for the GOP nominee. Exit polling was not available in that race.
In the closely watched race for New York City comptroller, exit interviews show Manhattan Borough President Scott Stringer running ahead of ex-Gov. Eliot Spitzer, who was seeking a return to politics after resigning New York's governor's office in 2008 amid a prostitution scandal.
The winner of the mayor's race in November will assume the helm of the nation's largest city at a critical juncture, as it experiences shrinking crime rates yet widening income inequality, and as the nearly completed One World Trade Center building symbolizes a new era after the terrorist attacks of 2001.
Mr. Bloomberg, the businessman Republican-turned-independent, is completing his third term. While the city's registered Democrats outnumber Republicans 6 to 1, the GOP's recent success in mayoral elections has been largely attributed to a crime epidemic, the aftermath of the Sept. 11 attacks or other extraordinary circumstances.
Nearly three-quarters of Democratic primary voters say the next mayor ought to move away from Mr. Bloomberg's policies, according to the exit polls.
And Mr. de Blasio, 52, has fashioned himself as the cleanest break from the Bloomberg years, proposing a tax on the wealthy to fund universal pre-kindergarten and changes to city police practices he says discriminate against minorities.
"I'm a lefty, and I've had enough of the righties," said Jessica Safran, a business consultant from Brooklyn's Boerum Hill section, who voted for Mr. de Blasio. "Even if de Blasio moves to the center if he gets elected, he'll be closer to the positions I want than the others."
Mr. de Blasio worked in Bill Clinton's White House and Hillary Rodham Clinton's Senate campaign before being elected to the city council and then public advocate, the city's official watchdog position.
"I liked what he said about the economic inequality in the city," said Norma Vavolizza, 65, who lives in the Bronx and works in marketing. "I think it's a serious issue that needs to be addressed.
All the candidates were hosting election night rallies in venues across the city. Each gathering went silent for 15 minutes when President Barack Obama addressed the nation on the situation in Syria.
Ms. Quinn, who was bidding to become the city's first female and first openly gay mayor, was the front-runner for much of the year, boasting the biggest campaign war chest and strong establishment backing. But she has been dogged by her support for changing term limits to let Mr. Bloomberg run again in 2009, a decision unpopular with liberals who make up the bulk of Democratic primary voters.
Turnout appeared light, but the city's complaint line received several thousand voting-related calls. Many reported jams and breakdowns in the antiquated lever machines, hauled out of retirement to replace much-maligned electronic devices.
The mayoral campaign was waged in hundreds of candidate forums and across millions of dollars of TV ads and was largely fought on the legacy of the Bloomberg era. Substantial policy differences were scarce among the Democrats, who agreed that the school system needed an overhaul, that the city's poor had been forgotten, and that stop-and-frisk police tactics used to stop suspicious people needed changing, amid claims that police unfairly targeted blacks and Latinos.
Mr. Thompson nearly defeated the billionaire mayor four years ago. This year, he ran a quiet, centrist campaign with hopes of receiving enough support from minorities to reach the runoff.
Mr. Weiner surprisingly entered the race after being in political exile since resigning from Congress in 2011..nation
