The Democratic primary for mayor of New York City, now a tight race among Eric Adams, Kathryn Garcia and Maya Wiley, will be decided by absentee ballots.Fresh off a vote-counting debacle that caught national attention, the chaotic New York City Democratic mayoral primary is moving into a new phase: the wait for absentee ballots.A preliminary, nonbinding tally of ranked-choice votes on Wednesday showed a highly competitive race, with Eric Adams, the Brooklyn borough president, holding a lead of about two percentage points over Kathryn Garcia, a former city sanitation commissioner. Under the ranked-choice elimination-round process, Maya Wiley, a former counsel to Mayor Bill de Blasio, finished just behind Ms. Garcia, trailing by fewer than 350 votes.But those results do not account for the roughly 125,000 Democratic absentee ballots submitted, and the race might look different once all eligible ballots have been accounted for.No one knows with any certainty how the absentee ballots will shape the outcome, though many political junkies and campaign officials are trying to game that out. Here is a look at what the data suggests, and a guide to what to watch for as New York moves closer to determining the Democratic nominee.When will we know who won?Final results are expected to arrive the week of July 12.Before that happens, the Board of Elections needs to finish counting the absentee ballots, a process that began on Monday. Those ballots that have been counted by July 6 will then be factored into a new ranked-choice tally that will be released on that date.The city’s new ranked-choice voting system allows voters to rank up to five candidates on their ballots in preferential order. Because Mr. Adams did not receive more than 50 percent of first-choice votes, the winner must be decided by a process of elimination: Lower-polling candidates are eliminated in separate rounds, with their votes distributed to whichever candidate those voters ranked next. The process continues until there is a winner.The board must also consider absentee ballots that were initially deemed invalid, as well as affidavit ballots that were filed on Primary Day by voters who were told they were ineligible, but cast provisional ballots that would be counted if they were later deemed eligible.So is it officially a two-person race?No. While Mr. Adams and Ms. Garcia were the last two candidates standing in the latest round of results released on Wednesday, those numbers were preliminary and could change as more absentee ballots are accounted for. Ms. Wiley remains in the mix.In Wednesday’s tally of ranked-choice voting, Kathryn Garcia took slightly more of Andrew Yang’s redistributed votes than Eric Adams.Andrew Seng for The New York TimesDid the campaigns push absentee voting?Yes.Advisers for all three of the leading campaigns said that they engaged in so-called ballot-chasing efforts: direct follow-ups with voters who had requested absentee ballots, reminding those voters to return the ballots. The results in coming weeks will offer a sense of who ran the most sophisticated campaign on that front.As voters requested absentee ballots, the Adams campaign sent them personalized letters — regardless of whether they believed those voters were ranking Mr. Adams as their first choice — and added those voters to their broader communications strategy, following up by email and phone, as well as by mail.Mr. Adams may also benefit from his significant institutional support. He was backed by several major labor unions, an often-important dynamic in turnout efforts, and his consulting firm has particular experience with absentee ballots: It assisted the Queens district attorney, Melinda Katz, in her 2019 race against Tiffany Cabán — a contest decided by absentee votes.The Wiley campaign used phone-banking and texting to urge Democrats who requested absentee ballots to send them in, focusing on absentee voters who they believed might support Ms. Wiley.The Garcia campaign also sought names of voters who requested absentee ballots and followed up with them by mail and phone. Absentee voting was also a factor in shaping the timing of outreach strategies like digital engagement, a Garcia adviser said.Eric Adams, the Brooklyn borough president, held a lead of about two percentage points over Ms. Garcia after a preliminary, nonbinding ranked-choice tally.Sarah Blesener for The New York TimesCould Mr. Adams still lose?In the first round of votes, among people who voted in-person early and on Primary Day, Mr. Adams was in first place, leading Ms. Wiley by 9.6 percentage points, and Ms. Garcia by 12.5 points. But when the preliminary ranked-choice tabulation was conducted, Ms. Garcia narrowly moved into second place and trailed Mr. Adams by only two points.It seems clear that the race is still an open three-way contest, but a final ranked-choice contest between Mr. Adams and Ms. Garcia, compared with Mr. Adams and Ms. Wiley, might play out very differently.Sparse polls and interviews with party strategists and voters have suggested that Ms. Wiley’s voters — especially in places like Brownstone Brooklyn — often ranked Ms. Garcia on their ballots. But Ms. Garcia’s voters, especially the more moderate ones, were not always inclined to rank Ms. Wiley as high. That dynamic, if it holds, could make it more challenging for Ms. Wiley to pull ahead of Mr. Adams, even if she did surpass Ms. Garcia.Ms. Wiley, who emerged as the favorite of younger left-wing voters, may have also found it more difficult to connect with some who vote by mail, a group that has traditionally included older voters.Still, she had a burst of momentum in the final weeks of the race, and the absentee ballots from her strongholds could help boost her numbers. While Ms. Garcia was the favorite in vote-rich Manhattan, Ms. Wiley came in second in the first round of votes, and could see her numbers rise in some neighborhoods as absentee ballots come in.She emphasized that the contest was far from over.“It is a wide-open race,” she said on Thursday. “We’ve known it was a wide-open race since Primary Day, and it remains a deeply competitive race.”“We’ve known it was a wide-open race since Primary Day,” Maya Wiley said on Thursday. Jose A. Alvarado Jr. for The New York TimesManhattan had the most absentee ballots. Whom does that help?Many of those ballots are likely to benefit Ms. Garcia, who, in the first round of voting, was dominant in Manhattan.For example, many people voted by mail in the affluent, well-educated neighborhoods that border Central Park — and among in-person returns, Ms. Garcia pulled off strong showings in those areas. Ms. Garcia, with her emphasis on competence over any ideological message, may have also been an especially strong fit for some types of absentee voters.“Historically, absentee ballots have tended to come from older, more highly educated, more affluent voters,” said Bruce Gyory, a veteran Democratic strategist who has closely studied the city’s electorate. He pointed to Garcia-friendly neighborhoods in Manhattan, Brooklyn and the Bronx. “Those are the kinds of voters who, particularly in Manhattan but also in the Brownstone belt, places like Riverdale, seem to have favored Garcia.”But on the first round of voting, Mr. Adams appeared to be the clear favorite in neighborhoods where many working-class Black and Latino voters live, and he also demonstrated some ability to connect with white voters with more moderate views.His allies argue that Ms. Garcia would have to pull in significant margins in Manhattan to cut into his expected lead in other parts of the city. The assembly districts where Mr. Adams had his strongest showings did cast fewer absentee ballots. But he led in more districts, and by higher margins, than Ms. Garcia overall.“It’s a fairly narrow path, and she would really have to overperform even in districts where she did well, in Queens and Brooklyn, and really run up the score in Manhattan,” said Neal Kwatra, who led a pro-Adams independent expenditure effort associated with a union representing hotel workers.Is there another key battleground?The second-largest number of absentee ballots were cast in Queens, where several candidates showed strength in the first round of voting.Mr. Adams, who won every borough but Manhattan in the first round, is likely to benefit from absentee ballots cast by Black homeowners in Southeast Queens, who tend to be more moderate. Ms. Wiley, who came in second place in Queens in the first round, was strong in Western Queens in particular, where many younger left-wing voters live; Ms. Garcia did well in places that are home to many white voters with more moderate views.Here is where ranked-choice voting may come into play.Andrew Yang, a former presidential candidate who has since dropped out of the race, did especially well in Asian American neighborhoods in Queens and elsewhere in the city. He spent the last days of the race campaigning with Ms. Garcia — but some voters may have cast their absentee ballots before that apparent alliance was struck.In Wednesday’s tally of ranked-choice voting, Ms. Garcia took slightly more of Mr. Yang’s redistributed votes than Mr. Adams. Ms. Garcia also took the vast majority of Ms. Wiley’s voters when her votes were reallocated.If those circumstances play out again, does that help Ms. Garcia significantly in Queens as well as in Brooklyn, where many absentee ballots are outstanding and where Ms. Wiley came out ahead of Ms. Garcia on the tally of first-place votes?“Queens seems to favor Adams, Manhattan favors Garcia — we don’t know who that balance is going to ultimately benefit,” Mr. Gyory said, allowing for the possibility that Ms. Wiley could pull ahead, too. Until the absentee ballots are “processed, opened and fully counted, I don’t think anybody should presume how they’re going to vote,” he added.Charlie Smart, Emma G.
