The top 10 neighbors for Richard Blumenthal form a tight cluster of journalists, academics, and fellow politicians — with no single neighbor pulling far ahead of the rest. Similarity here measures how closely two entities' audiences resemble each other in composition; the scores across Blumenthal's top 10 span just 0.97 to 0.94, a narrow band consistent with the flat shape.
Sheldon Whitehouse leads at 0.97, followed closely by Laurence Tribe (0.95) and Stephanie Ruhle (0.95). Journalists make up the largest single subcategory in the top 10 — Ruhle, David Corn, and Mika Brzezinski all appear — alongside two academics (Tribe and Richard W. Painter), two fellow politicians (Whitehouse and Chris Murphy), one government official (John O. Brennan), one TV personality (Mimi Rocah), and one blog (Rachel Maddow Blog). Only two of the ten neighbors share Blumenthal's own subcategory of Politicians; the majority are journalists and legal or political commentators operating outside elected office.
The flat, cross-kind shape suggests Blumenthal's audience is defined less by partisan political identity alone and more by a broader orientation toward political-legal commentary and accountability journalism.
