Pete Buttigieg's top 10 nearest neighbors are a cross-kind mix of journalists, comedians, actors, and activists — with only one fellow politician in the set. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 0.98 indicates near-identical audience shape.

The shape is flat: scores run from 0.9879 (Daniel Dale) down to 0.9750 (Jen Psaki), a spread of just 0.013 across all ten neighbors. No single entity dominates. Journalists make up the largest subcategory block — Dale (0.9879), Aaron Rupar (0.9833), and Kaitlan Collins (0.9755) — but they share the tier with Bradley Whitford (0.9834, Actors), The Onion (0.9814, Websites), The Late Show (0.9810, TV Shows), Sarah Cooper (0.9804, Comedians), Shannon Watts (0.9760, Activists), and Chasten Buttigieg (0.9827, Professionals). Jen Psaki (0.9750) is the lone politician in the top 10. The absence of other politicians at the top of this list — and the presence of late-night TV, political satire, and fact-checking outlets — defines the cluster's character more than any single neighbor does.

The audience this shape describes is one organized around political media consumption broadly, not around a politician's own peer group.
