The race is part of the 2026 Democratic primary scheduled for Tuesday, June 23, 2026, and has become a sharper test of progressive energy against a long-serving Democratic incumbent.

Chevalier Biden Posts Resurface in NY-13 Race

Reports published Friday, May 29, 2026, said deleted posts from an X account attributed to Chevalier included harsh criticism of former President Joe Biden during the 2020 election cycle.

One reported post criticized the choice facing voters during the Biden-Trump race and referred to sexual misconduct accusations involving both men. Another reportedly said Chevalier, who had voted in every election since turning 18, would not vote for someone she described as a “war criminal.”

The resurfaced remarks are now becoming part of the campaign conversation as Chevalier’s profile rises in the NY-13 Democratic primary.

Mamdani Endorsement Raises Chevalier’s Profile

Mamdani’s endorsement gives Chevalier a larger platform among left-wing and democratic socialist voters. It also places new attention on how her campaign handles past online statements as she seeks to build support beyond activist circles.

Chevalier is challenging Espaillat, a five-term Democrat and major figure in New York politics. The district includes parts of Upper Manhattan and the Bronx, making the primary closely watched by both progressive groups and Democratic establishment allies.

Espaillat Challenge Reflects Democratic Party Tensions

The race now reflects a broader divide inside the Democratic Party: whether insurgent progressive candidates can turn grassroots energy into congressional victories against experienced incumbents.

For Chevalier, the Mamdani endorsement may help with visibility and organizing. But the renewed scrutiny over her Biden posts could also test whether voters view her past remarks as political conviction, online controversy, or a campaign liability.
