Communications

The Mamdani Franchise — an independent, non-partisan, open-source playbook. Not affiliated with the Mayor of New York City, the City of New York, or any campaign or party. Status: DRAFT v0.1 (Stage 2 synthesis) · Evidence cut-off: 2026-11-10.

Evidence IDs refer to rows in the evidence register. Every claim cites an ID with URL and date; unverified items are marked [UNVERIFIED]. Poll figures are reported as published; favorability and job approval are different measures and are labeled.

Summary disclosure

The administration carried a campaign-built social audience into government and built a communications operation around it:

• Structure: a Communications Director overseeing the press office, digital, new media and agency communications (EV-251), plus an Office of New Media and Cultural Communications that recruits creators, neighborhood pages and community outlets (EV-252).
• Scale of creator outreach: the NYT reported City Hall has worked with more than 1,200 content creators and coordinates 250+ influencers in group chats (EV-140).
• Formats: self-produced video (often posted before press coverage), multilingual posts, a live-streamed Q&A on Twitch/YouTube/TikTok, an official 100-day tracker, and reinstated TikTok use by agencies under security rules (EV-253 EV-091 EV-088 EV-085 EV-082 EV-083).

Results: NYC favorability rose from the 50s in spring to 69% in October 2026 (Siena), while job approval in April was 43–48% depending on the pollster, below Adams' 61% at the same point (per the NYT) (EV-089 EV-255 EV-147 EV-254).

Costs and critiques: the first City Hall press conference admitted only "new media" creators (EV-080); reporters described closed-press events with favored outlets tipped off (EV-253); watchdogs raised records-retention and transparency concerns about the influencer program, and City Hall declined to disclose its budget or list (EV-140).

Transferability: the operating model (an in-house creator desk, direct video, multilingual posts, a public tracker) is low-cost and transfers widely. The audience does not: NYC started with millions of followers built during the campaign (EV-078 [UNVERIFIED]).

Channel and format inventory

Public opinion over time

The August figures are confirmed by Siena's own release; the 58–26 / 45–34 figures reported on Aug 12 by one outlet were Siena's June results.

Reading the table: NYC figures in the Siena and Quinnipiac rows are subsamples of statewide polls. The two direct job-approval readings (spring) were lower than the favorability readings later in the year, and they measure different things. No causal link between communications tactics and opinion is claimed.
