Later in the week, internal turmoil from the Morales campaign spilled into public view, and it is not yet clear how a late-stage campaign shake-up nearly three weeks before the primary will affect that standing.
Ms. González-Rojas, however, said on Wednesday that she stood by her remarks. She has also said that she had pitched Ms. Morales’s candidacy to Ms. Ocasio-Cortez’s team.
Ms. Ocasio-Cortez, who is of Puerto Rican descent, is among the most powerful potential endorsers still remaining on the sidelines of the mayoral race. Ms. Velázquez, who has recorded radio ads on behalf of Ms. Wiley, has spoken with Ms. Ocasio-Cortez directly about the contest, encouraging her to meet with Ms. Wiley, she said.
Other candidates are also ramping up their Latino engagement. Ms. Wiley released an agenda aimed at Latino communities last week. In his new ad, Mr. Donovan narrates in Spanish, and he visited a major Latino church in Queens this weekend. Raymond J. McGuire, a former Citi executive, has Spanish-language radio ads and the support of, among others, Assemblyman Robert J. Rodriguez of East Harlem.
Mr. Stringer, for his part, has long seen opportunities to cement his standing with Latino voters in the final weeks of the race. He lost Mr. Espaillat’s backing, among others, following an accusation that he made unwanted sexual advances during a 2001 campaign, which he has denied.
But even lawmakers who retracted their endorsements say that Mr. Stringer remains well known in some of their neighborhoods.
He is planning a rally aimed at Latino voters in Washington Heights, where he grew up, on June 12. His stepfather, Carlos Cuevas, is Puerto Rican and narrates a Spanish-language ad for Mr. Stringer, and Mr. Stringer’s extended Puerto Rican family is expected to join him at the rally, his campaign said.
Many Latino voters are just starting to take notice of the race, said Assemblywoman Catalina Cruz of Queens, who pulled her endorsement from Mr. Stringer and has not backed anyone else. “They don’t really start talking about the election until like a month out,” she said. “You will see them start paying a lot more attention in the couple weeks leading up to the election itself, unless there’s somebody that completely electrifies them.”
