Sen. Bernie Sanders (I-Vt.) and New York City Mayor Zohran Mamdani joined forces at a get-out-the-vote rally on June 20, aiming to boost three progressive congressional candidates ahead of the primary elections scheduled for Tuesday, June 23.

The endorsed candidates include political organizer Darializa Avila Chevalier, who is challenging Rep. Adriano Espaillat (D-N.Y.) in New York's 13th District; former New York City Comptroller Brad Lander, running against incumbent Democratic Rep. Dan Goldman in the 10th Congressional District; and democratic socialist state Assembly Member Claire Valdez, who is battling Brooklyn Borough President Antonio Reynoso in New York’s 7th District.

The rally, held in Brooklyn, is designed to elevate a slate of candidates aligned with Mamdani's values, including two running against Democratic incumbents in Tuesday's primary. According to PBS, Faiz Shakir, a senior adviser to Sanders and a friend of Mamdani's, stated that the mayor is seeing an opportunity 'to radically change the Democratic Party.' Establishment Democrats are not pleased with the mayor's decisions.

The endorsements have upset moderate Democrats, especially Mamdani's decision to switch his allegiance from Espaillat to Chevalier. According to Fox News, House Minority Leader Hakeem Jeffries has tried to push back against the Mamdani-backed democratic socialist challengers, endorsing and campaigning for the embattled incumbents in a proxy fight with the mayor.

The outcomes of these races will test whether Mamdani's popularity among New York Democrats translates into coattails in elections. Republicans plan to use Mamdani's socialist brand against vulnerable House Democrats in swing districts, according to both PBS and Fox News. The GOP believes the specter of the New York City mayor will loom large in pivotal House races in New York and New Jersey.

The rally comes as democratic socialists are flexing their growing political strength across the nation. According to Time, Janeese Lewis George, a D.C. Council member and Democratic Socialist of America (DSA) member, is leading in vote counting in Washington, D.C.'s mayoral primary. If her lead holds, she will likely replace Mayor Muriel Bowser as the city's leader in January. This victory would mark another significant win for the DSA, following Mamdani's election as mayor of New York City.

The DSA's influence is expanding, with more candidates identifying as democratic socialists or aligning themselves with the organization's platform. The group's membership has grown significantly since 2016, rising from around 5,000 to over 100,000 now. This growth is largely driven by young and urban members who are excited about the prospect of having control over local politics.

The DSA's expanding influence is forcing a power struggle with establishment Democrats, as prominent democratic socialists like Rep. Alexandria Ocasio-Cortez work to push the party further left through endorsements in Democratic primaries. The organization faces challenges in handling politicians who champion its policies but distance themselves from identifying as democratic socialists.
