The top 10 neighbors for Diane Rehm: On My Mind span journalists, government officials, academics, and fellow podcasts and radio programs — with no single standout pulling away from the pack. Similarity scores run from 0.92 at the top down to 0.91 at position 10, a band of less than two hundredths of a point across the entire set. (Similarity here measures how closely two entities' audiences resemble each other in composition, on a 0–1 scale.)

Journalists dominate the cluster: Nina Totenberg (0.92), Mary Louise Kelly (0.92), Kristen Welker (0.91), EJ Dionne (0.91), Luke Russert (0.91), Jake Tapper (0.91), and Kaitlan Collins (0.91) all appear as journalists. The remaining three positions go to Doug Emhoff (0.92) as a government official, Morning Edition (0.92) as the lone fellow podcast and radio program in the top 10, and Larry Sabato (0.91) as an academic. The center entity's own subcategory — Podcasts and Radio — has exactly one representative in the top 10, meaning the audience shape is defined far more by political journalism and public affairs figures than by other audio programs.

The flat shape here reflects an audience that is deeply embedded in a specific media-and-politics ecosystem, drawing equally from across its constituent parts rather than anchoring to any single node within it.
