Jeff Flake's ten nearest neighbors by audience shape span three distinct subcategories — politicians, journalists, and academics — with no single kind dominating the set. Similarity here measures how closely two entities' audiences resemble each other in composition; scores across the top 10 run from 0.96 to 0.96, a narrow band consistent with the flat shape classification.
Bill Kristol (0.96) and Rick Wilson (0.96) are the two closest matches, both classified as Politicians, joined by John Dean (0.96) as the third politician in the set. Journalists account for three more slots: Matthew Dowd (0.96), Jennifer Rubin (0.96), and Matthew Miller (0.96). Academics fill two positions — Neal Katyal (0.96) and Laurence Tribe (0.96) — with John O. Brennan (0.96, Government Officials) and Steve Schmidt (0.96, Professionals) rounding out the ten. The spread across subcategories means no single professional type defines the audience neighborhood; journalists and academics together match the count of fellow politicians in the top 10.
The flat shape and tight score band indicate an audience that overlaps broadly and evenly across political commentary, journalism, and legal-academic commentary rather than clustering tightly around any one kind.
