David Friedberg made this comment about Zohran Mamdani’s upset win in the NYC Democratic mayoral primary on the June 28, 2025 episode of the All-In podcast, calling it “the beginning of a wave that will sweep over [America].”(speakai.co) The user’s normalized prediction frames this as a decade‑long shift toward majority support for socialist‑style policies across much of the U.S. As of today (November 30, 2025), barely five months have passed since the prediction, and the relevant time horizon—“over the next decade,” i.e., through roughly 2035—has not elapsed. Because this claim is about long‑term national political realignment rather than immediate election outcomes, there is not yet enough elapsed time or data to fairly determine whether such a broad wave has materialized or failed, so the prediction must be considered too early to judge.
