Progressive Wave Sweeps New York: Mamdani-Backed Candidates and Hochul Secure Key Victories in 2026 Midterms

In a significant political development, progressive candidates endorsed by New York City Mayor Zohran Mamdani have achieved decisive victories, securing seats in the United States Congress. New York City politicians Brad Lander, Darializa Avila-Chevalier, and Claire Valdez have officially won their respective races for the 10th, 13th, and 7th districts in the 120th Congress. These wins, following their strong performances in the state’s June 23 party primaries, were largely anticipated given the heavily Democratic leanings of their districts. However, their success in the 2026 midterm elections undeniably solidifies a notable political shift within the New York City area, a movement catalyzed by Mamdani's own victory as a democratic socialist in the 2025 mayoral race.

“The national story is about this new generation of progressive leaders and getting excited about those who will be inspired by them just as they were inspired by Mamdani,” stated Adin Lenchner, a progressive political strategist for Carroll Street Campaigns. “Brad, Darializa and Claire are on their way to help lift up that same vision of progressive leadership in DC.”

Democratic Congressional candidate Claire Valdez addressed the public on Tuesday, discussing key policy issues, including President Donald Trump’s earlier pledge to halt annual military aid to Israel by the end of the year. This proposed cessation of aid was a cornerstone of Valdez's, and indeed all three candidates', policy platforms, reflecting their opposition to the ongoing conflict in Gaza. “I don’t know that we can trust this president to make moral and consistent decisions about our military budget, so we’ll have to see,” Valdez told Al Jazeera. Valdez, who will transition to Congress from the state assembly, began her political career in the labor movement, advocating for policies that facilitate union organization. She secured her victory against Republican community activist Melvin Rivera in a decisive race.

Elsewhere, US Representative Alexandra Ocasio-Cortez, a prominent progressive elected in 2018, also handily won her House race for the 14th congressional district. Other notable House of Representatives wins include Micah Lasher, a New York Assembly member who will now serve his first term in Congress after defeating Republican challenger Caroline Shinkle. Incumbent Representative Grace Meng in Queens, New York, also successfully defended her seat against Republican challenger Joseph Chou. Meng characterized the broader Democratic sweep in the midterms as “a mandate for us, not just a promotion,” emphasizing that a primary goal for the new Congress will be to challenge President Trump’s actions. “He has not treated Congress like a third and independent branch of government and is just going around doing whatever he wants,” Meng remarked.

New York Democrats are also advocating for Hakeem Jeffries, the longtime representative for the state’s 8th congressional district, to be selected as the next House speaker. Jeffries currently holds the position of House minority leader. His potential selection would mark a historic moment, making him the first Black speaker of the House of Representatives. “We are going to course-correct, and my good friend Congressman Hakeem Jeffries is set to wield the speaker’s gavel,” New York State Attorney General Letitia James announced following her own re-election victory on Tuesday.

In addition to the congressional races, the state of New York saw incumbent Democrat Kathy Hochul win re-election as governor. She defeated Republican Bruce Blakeman, whose platform focused on tax cuts and immigration reform. Hochul and Adrienne Adams have made history as the first all-woman ticket to win election as governor and lieutenant governor in New York. Hochul, who has held the gubernatorial post since 2021, and Adams, formerly of the New York City Council, celebrated their victory. Hochul directly addressed Trump in her victory speech, referencing his campaign efforts in New York. “Just a few weeks ago, Donald Trump came to New York and told voters to pretend he was on the ballot,” Hochul stated. “Well, Mr President, you got your wish.” Hochul’s new term commences on January 1, 2027, with the new congressional leaders set to be sworn in on January 3, 2027.
