First came the fevered pitch of the warm-up speeches and the catchy campaign jingle, in English and Spanish, which rang through the air at the park just south of City Hall. The New York City mayor’s race was approaching a pivotal moment, and Eric Adams, one of the top candidates, seemed prepared to seize it.
Mr. Adams proclaimed his readiness for a brutal final stretch of the mayoral primary — and, in ways implicit and overt, proceeded to rip into the track record of Andrew Yang, his chief rival, as he sketched out his own vision for the city.
Just a day earlier, Mr. Yang, whose campaign has been typified by congeniality and optimism, lashed out at Mr. Adams’s fund-raising practices, in his most direct criticism of an opponent to date.
Other attacks came from Scott M. Stringer, the city comptroller, who laced into both Mr. Adams and Mr. Yang for currying favor from “hedge-fund billionaires,” and challenged Mr. Yang over education issues. And Maya D. Wiley held a news conference last week to skewer Mr. Yang over his knowledge of policing matters.
Four weeks before the June 22 Democratic primary that will almost certainly determine New York City’s next mayor, the race is approximating a traditional campaign brawl after months of somewhat passive but decorous exchanges over video forums.
For much of the race, Mr. Yang, the former presidential candidate, has led the sparse public polling, and most of the broadsides from other candidates have been aimed at him.
But Mr. Adams, the Brooklyn borough president, has increasingly appeared to occupy at least as much of his rivals’ head space — a reflection of his strength in the contest.
“You don’t aim at what’s weak, you aim at what’s strong,” said Donovan Richards, the Queens borough president who is supporting Mr. Adams, ahead of his City Hall rally. “We’re moving into the final stretch and the race will intensify more, but clearly he’s resonating.”
The next mayor of New York will play a central role in determining how the nation’s largest city recovers from the pandemic and overlapping crises concerning the economy, inequality and public safety. Aware of those stakes, the candidates are racing to press their cases, bombarding voters with flurries of campaign literature, accelerating in-person campaign schedules and sharpening their contrasts with each other.
Since Jan. 1, there has been more than $24 million in Democratic spending in the mayor’s race, according to AdImpact, an advertising tracking firm, including a flood of outside spending on behalf of several of the candidates. A number of the contenders still have significant war chests available to fuel a barrage of ads through the end of the race.
According to political strategists, advisers to the candidates and the public polling available, Mr. Yang and Mr. Adams are generally seen as the front-runners, but another candidate could still surge, even at this late stage.
Kathryn Garcia, the former sanitation commissioner, is working to build momentum after endorsements from the editorial boards of The New York Times and The New York Daily News, and she has shown some traction in the limited available polling.
Ms. Wiley, who delivered an assertive debate performance, released her second ad last week, and is seeking to build a coalition that includes Black voters and white progressives. She is competing with Dianne Morales, a former nonprofit executive, to emerge as the left-wing standard-bearer in the race, a position Mr. Stringer had hoped to occupy.
An accusation that Mr. Stringer made unwanted sexual advances during a 2001 campaign, which he denies, has derailed that ambition, with several key left-leaning supporters rescinding their endorsements. For the last fund-raising period, he raised less than the seven other leading candidates, though his campaign noted that the haul was bigger than that of the preceding two-month period.
Mr. Stringer remains well-funded, is advertising extensively and has the support of some powerful unions. He has also received air cover from a super PAC associated with teachers’ unions.
Raymond J. McGuire, a former Citi executive, and Shaun Donovan, the former federal housing secretary, are also well-funded candidates with active campaign schedules and the support of super PACs who are looking for ways to break out. In the last fund-raising period, Mr. McGuire, Mr. Yang and Mr. Adams appeared to pull in the most money, though Ms. Wiley and Ms. Garcia in particular showed growth compared with the previous period.
The arrival of ranked-choice voting in New York City, in which voters can rank up to five candidates in order of preference, has also injected a measure of significant uncertainty into the contest — and on the ground, there are signs that many voters have not yet made decisions about their first choices, much less the rest of their ballots.
There are two more official Democratic debates scheduled — one is for “leading contenders” — that may help voters decide, though the candidates are frustrated that the June 2 matchup is slated to be virtual. And in the final weeks, key influencers like Representative Hakeem Jeffries, who endorsed Ms. Wiley, are now choosing sides.
On Sunday, Representative Adriano Espaillat, a prominent Dominican-American lawmaker who pulled his endorsement of Mr. Stringer, announced his support for Mr. Adams — a decision that was being closely watched as the battle for Latino voters intensifies.
Other high-profile Democrats are weighing how best to use their influence as the four-week countdown arrives. State Senator John C. Liu of Queens, an influential voice in New York Asian-American politics, is expected to endorse Mr. Yang on Monday, according to a person familiar with the matter. Representative Grace Meng, the highest-ranking Asian-American elected official in New York, also backed Mr. Yang earlier this month.
“I was leaning toward not endorsing, I’m leaning more toward it now,” said Jumaane D. Williams, the public advocate.
“If I do endorse it would be a combination of where I think I ideologically align and who I think shouldn’t run the city,” or, he added, “who I’d have concerns about running the city.”
