Nine of Paul Begala's ten nearest neighbors are journalists, not fellow politicians — a composition that defines the shape of this audience more than any single score does. Similarity here measures how closely two entities' audiences resemble each other in composition; the top 10 span a narrow band from 0.9774 to 0.9842, with no single neighbor pulling away from the rest.
Robert Costa leads at 0.9842, followed closely by Manu Raju (0.9814), Dana Bash (0.9800), Ashley Parker (0.9791), Chris Cillizza (0.9790), David Frum (0.9783), Jonathan Karl (0.9780), Betsy Woodruff Swan (0.9775), and Peter Baker (0.9774) — all journalists. The one exception in the top 10 is David Axelrod (0.9837), the only fellow politician in the set. The cluster is otherwise entirely political journalists and correspondents, spanning print, broadcast, and digital outlets.
The flat shape and the journalist-heavy composition together suggest an audience that follows political coverage as a category, treating a strategist-commentator and the reporters who cover the same beat as functionally interchangeable in their attention habits.
