Mondaire Jones, a progressive candidate supported by the institutional left, was declared the victor in a crowded Democratic House primary in the suburbs north of New York City, all but ensuring that he will join Congress next year as among its first openly gay African-American members.
The race was not called by The Associated Press until Tuesday, three weeks after the primary, even though Mr. Jones had a commanding advantage after the machine ballot count: He had twice as many votes as his closest competitor, Adam Schleifer.
Mr. Jones’s support grew as Primary Day drew closer, as Black Lives Matters protests galvanized voters across the district and allowed candidates, for the first time since the pandemic, to campaign in the open air.
