Zohran Mamdani grabbed the national spotlight midyear when he won New York City’s Democratic mayoral primary, defeating former Gov. Andrew Cuomo. As the city prepares for the mayoral election in November, voters are closely watching the promises Mamdani is making to win support.
One of Mamdani’s key campaign promises is the creation of city-owned grocery stores. “As Mayor, Zohran will create a network of city-owned grocery stores focused on keeping prices low, not making a profit,” his campaign website says. “Without having to pay rent or property taxes, they will reduce overhead and pass on savings to shoppers.”
Mamdani’s proposal appears to be gaining traction. A March 2025 survey of 854 likely New York City voters found that two-thirds support the creation of municipal grocery stores.
However, critics of Mamdani — including John Catsimatidis, CEO of the New York-based supermarket chains Gristedes and D’Agostino and a vocal supporter of President Donald Trump — say they doubt it will work. Catsimatidis, who has threatened to close the Gristedes chain if Mamdani is elected mayor, said there are many variables involved in running a grocery store in a city.
“He has a great smile and a great gift of talking,” said Catsimatidis, “but no clue about what the real world is all about.”
City-owned grocery stores are not a new concept in the United States. St. Paul Supermarket in St. Paul, Kansas, stands out as a successful example.
“I think city-funded grocery stores are a good idea where they are needed,” said St. Paul Mayor Keith VanLeeuen. “We have a small town. It was a necessity for us.”
However, just 10 miles away, Erie Market offers a stark contrast, having closed its doors after several consecutive years of losses.
“In 2020, we purchased the Erie Market grocery store in Erie, Kansas, and we had one profitable month, and then after that, we were bleeding. We made no profit,” said Erie City Mayor Lester “Butch” Klingenberg. “And this went on clear through 2024, and we had to lease it out, lease it out or close it.”
