New York City Mayor Zohran Mamdani told residents to turn their air conditioners up to 78 degrees as a brutal heat wave bore down on the city, and Republicans wasted no time making him the face of progressive energy policy gone wrong.
Mamdani posted the request on X, citing strain on the power grid and urging New Yorkers to unplug electronics and turn off lights. Within hours, a parade of prominent conservatives, from a sitting U.S. senator to a former presidential candidate to a media mogul who has floated running against Mamdani, piled on with pointed responses about socialism, communism, and what life looks like in a city run by the left.
The mayor framed his appeal as a civic duty. His critics framed it as an admission of failure. And the Department of Energy's own thermostat guidance, which recommends the same 75-to-78-degree range Mamdani cited, didn't stop the political firestorm from spreading faster than the heat index.
The mayor's post, published Wednesday ahead of what USA Today described as a multi-day forecast of extreme temperatures stretching through the holiday weekend, laid out a series of conservation steps. He opened with a straightforward appeal:
"New York: it's hot out there, and the power grid is working overtime to keep us cool. Set your AC to 78 degrees, turn off lights/electronics you're not using, and unplug what you can."
Mamdani went further, announcing that city government would follow its own advice. City buildings would hold to the 78-degree rule. Lights in municipal facilities would be dimmed or shut off during peak electricity demand. Private partners were being asked to power down non-essential equipment.
He closed with a plea for collective action, writing that "a stable grid means the AC stays on, and lives are saved."
Whether the request was purely advisory or carried any enforcement mechanism remains unclear from the mayor's post. But the political damage was already done.
Vivek Ramaswamy, the Republican candidate for governor of Ohio, turned the moment into a campaign pitch. He posted on X:
"This is what socialism looks like, folks. The right answer isn't restrictions or mandates. It's drilling, fracking, coal, & nuclear. That's how we'll roll in Ohio."
Former presidential candidate Nikki Haley kept it short: "Welcome to socialism."
Texas Sen. Ted Cruz offered a dry jab that drew its own complications. He wrote, "In a first-world country, you could turn on the A/C." Users quickly added a community note to Cruz's post pointing out that Texas has also asked residents to set their thermostats to 78 degrees in the past, a detail that undercut the senator's framing, even if it didn't erase the broader point about grid reliability.
Barstool Sports founder Dave Portnoy, who has said he is considering a run against Mamdani for mayor, was the most colorful. He posted: "78 degrees??? Welcome to communism people! Hope you enjoy!"
There is an inconvenient detail for the critics, and Mamdani's defenders have seized on it. The U.S. Department of Energy's own recent guidance suggests starting AC thermostats at 75 to 78 degrees in summer, and raising the setting higher when no one is home. Mamdani's 78-degree recommendation falls squarely within the federal government's own range.
That fact complicates the "socialism" framing, at least on the specific number. The DOE guidance is a suggestion, not a mandate, and it applies nationally, not just in blue cities. But it also doesn't change the underlying question: why is New York City's power grid so fragile that the mayor has to beg eight million people to sweat a little more just to keep the lights on?
The New York Post reported that the heat wave was expected to push temperatures to 100 degrees, and that critics mocked the recommendation as hypocritical, particularly given that Times Square remains illuminated around the clock. The Post also noted that Mamdani's predecessor, Eric Adams, issued the same 78-degree guidance in 2023.
That last detail is worth sitting with. If the same request has to be made year after year, by mayor after mayor, it stops looking like an emergency measure and starts looking like a structural problem no one in City Hall has bothered to fix.
For Mamdani, the AC flap is the latest in a growing list of moments that have put him on the defensive. The mayor has already drawn scrutiny over ethics questions involving free World Cup tickets, and his willingness to push ideological boundaries has not gone unnoticed even within his own party.
Breitbart framed the thermostat request as evidence of either gross incompetence in managing the city's energy infrastructure or a manufactured crisis used to control citizen behavior. That's a pointed reading, but it lands because the mayor offered no explanation of what went wrong with the grid, only instructions for how residents should compensate for whatever did.
New York Attorney General Letitia James has previously accused Mamdani of damaging the Democratic Party with socialist endorsements, a charge that gains fresh resonance when multiple Republicans can plausibly label his governing style as socialist and point to a concrete example.
The mayor's approach to governance has raised eyebrows on other fronts as well. His refusal to enforce a Supreme Court ruling on deportation protections signaled a willingness to defy legal authority when it clashes with his ideological commitments. And the recent $126 billion budget deal with the City Council, in which Mamdani reportedly caved on NYPD expansion, raised questions about whether the mayor's priorities align with the practical needs of the city he runs.
Strip away the social media theatrics on both sides, and the core issue is simple enough: New York City, the financial capital of the Western world, cannot keep its air conditioning running during a heat wave without asking millions of residents to sacrifice comfort.
Mamdani didn't explain why the grid is under such strain. He didn't announce new generation capacity, emergency procurement, or infrastructure upgrades. He asked people to sweat, and told them the city would dim the lights.
Republicans scored easy points. Some of them, Cruz, in particular, scored points that boomeranged when their own states' track records surfaced. But the underlying critique holds: when your answer to summer heat in one of the richest cities on earth is "turn your AC up and unplug your toaster," something has gone badly wrong with how that city is governed.
The DOE may recommend 78 degrees as a baseline. Fine. But there is a difference between a federal suggestion for routine energy efficiency and a mayor pleading with residents to conserve power so the grid doesn't buckle. One is guidance. The other is a distress signal dressed up as civic responsibility.
Moshe Spern, president of the United Jewish Teachers, captured the mood of many New Yorkers when he posted, as the New York Post reported: "Only a Communist believes distribution of wealth also means distribution of air conditioning."
Whether that's fair or not, Mamdani handed his opponents the line. He told the biggest city in America to turn down the AC and hope for the best. In July. Heading into a holiday weekend.
When the people running the city can't keep the power on without rationing comfort, the problem isn't the thermostat setting. It's the people who never built the grid to handle the load.
