Missing from the left

A reader who follows the left would not have seen this. We report the absence rather than explain it: outlets choose what to cover for many reasons, and we have no evidence about which one applies here.

New York City Mayor Zohran Mamdani proposed a surtax on owners of multiple homes, American Greatness reported. The policy targets property owners who cannot prove full-time occupancy of their homes. Mamdani published a list of nearly one million New York homeowners and sent official warnings to 17,000 of them. The surtax could add between $40,000 and $350,000 annually to their property taxes.

The mayor’s office framed the policy as a measure to redistribute housing. American Greatness reported that Mamdani aims to force a fire sale of second homes, lowering property values to make housing more affordable. The warnings gave property owners four weeks to prove full-time occupancy or face the surtax. The policy reverses the legal presumption of innocence, requiring owners to prove they are not hoarding housing.

American Greatness reported that the surtax would be in addition to existing property taxes, which already range from $5,000 to $150,000 annually. The outlet calculated that the combined tax burden could exceed the value of some properties within a few years. The list of targeted owners included their addresses, which American Greatness said could expose vacant homes to squatters or criminals.

What the coverage left out

None of the left- or centre-rated outlets below carried this story. The right-rated digests and report did not include any statement from Mamdani’s office explaining the policy’s goals or legal basis. Neither did they quote housing policy experts, city officials outside the mayor’s office, or property owners affected by the warnings.

  • The two right-rated reports led on Mamdani’s policy as an example of socialist or communist governance. American Greatness described the surtax as an attempt to confiscate private property and framed the mayor’s actions as part of a broader agenda to dismantle capitalism. The outlet quoted Mamdani’s warning to property owners and described the policy as a reversal of the legal principle of "innocent until proven guilty."
  • American Greatness used the phrase "enemies of the people" to describe how Mamdani’s policy targets property owners. The outlet called the list of homeowners a "doxing" effort and said the mayor’s aim was to "flush out" owners of second homes. It also described the policy as a step toward "show trials" for those who resist. The digest of victorhanson.com carried the same framing, describing the policy as part of a pattern of socialist governance.
