New York's Mayor Is Backing Challengers in Congress
New York Mayor Zohran Mamdani is endorsing candidates to run for Congress in an election this June. One of his picks is challenging a sitting Democratic congressman from his own party.
Mamdani endorsed Darializa Avila Chevalier to run against Congressman Adriano Espaillat, according to Reuters (June 23). Mamdani is trying to get more progressive politicians elected to Congress by replacing a Democrat who is already in office.
On June 19, Mamdani and Senator Bernie Sanders held a rally in Brooklyn for three candidates: Avila Chevalier, Brad Lander, and Claire Valdez. NY1 reported on the event. Sanders's presence matters because he brings a national network of supporters and money that the mayor's endorsement alone cannot deliver.
News outlets viewed this move differently. Reuters said it tests whether New York voters want more progressive candidates in Congress. CNN said it measures how much influence Mamdani has with voters overall. Both are asking the same question: can a mayor who won based on progressive politics get the same result in races he doesn't directly control?
What's at Stake
Challenging an incumbent from your own party is risky. If Avila Chevalier loses, Mamdani looks bad for backing a failed candidate. If she wins, he gets credit for an important victory.
Espaillat has held his congressional seat since 2017 and is well-established in his district. Incumbents have major advantages — voters know their name, they have money to spend, and they have existing connections with their communities. Mamdani is betting his endorsement plus Sanders's supporters can overcome those advantages.
The other two endorsements are less risky. Lander already ran for mayor and many voters know him. Valdez is less well-known. Together, they show a mayor trying to build a lasting coalition of allies in Congress.
The June election will answer a basic question: how much power does a mayor's endorsement actually carry outside City Hall? Winning the mayoralty is one thing. Getting candidates elected to Congress in districts he doesn't represent is another.
