78° Thermostat Post — Viral Backlash and City Hall Spot-Check

Mamdani's Jul 2 X post asking New Yorkers to set thermostats to 78° during the extreme-heat dome amassed 36.5M+ views by the weekend and became a national flashpoint. Republicans (governors, Fox, conservative pundits) branded it "communist"; energy experts and the mayor's office noted the 78° figure is the standard DOE recommendation used by prior NYC administrations. NY Post spot-check found 15 of 20 City Hall locations sampled were below 78° — undercutting the mayor's ask on his own turf. Not a governance failure, but a communications-and-optics wound during an otherwise-clean first heat-emergency operational run.
