Above, WNYC's Brigid Bergin discusses where the mayoral race goes from here.

Mayor Bill de Blasio is a step closer to winning a second term.

With nearly all precincts reporting as of early Wednesday morning, de Blasio had nearly 75 percent of the vote in the Democratic primary.

Former City Councilman Sal Albanese, the leading Democratic challenger, was running second with just over 15 percent, followed by Mike Tolkin, a tech entrepreneur; Robert Gangi, a criminal justice reform advocate; and Robert Bashner, an attorney.

In his post-election party, at an event space in Downtown Brooklyn, the 6-foot-6-inch de Blasio indicated he would continue expanding his liberal policies in order to, as he put it, "pass prosperity around."

"We have more to do," he said in his 21-minute victory speech. "We have ways to still build a fairer city. I'm not going to stop until we do."

De Blasio will face Republican Nicole Malliotakis, as well as candidates from other parties, in the November elections. In her attack ads, Malliotakis has been attacking de Blasio for his alleged fondness for afternoon naps.

In other races:

• Public Advocate Letitia James; Bronx Borough President Ruben Diaz, Jr.; and Acting District Attorney Eric Gonzalez all secured the Democratic nomination.
• In Queens, Hiram Monserrate, a former City Council member and state Senator who was found guilty of assaulting his girlfriend and misusing public funds, lost his bid to retake his council seat;
• On Manhattan's Upper West Side, incumbent Helen Rosenthal defeated Mel Wymore in the Democratic primary for City Council;
• Council races in East Harlem (District 8) and Lower Manhattan (District 1) were decided within 200 votes — a margin that could be erased once affidavit and absentee ballots are counted.
