The top 10 neighbors for Sherrod Brown form a tightly compressed band — similarity scores run from 0.90 down to 0.86 with no single dominant outlier — and the mix of subcategories is the real story here.

The shape is flat: John Fetterman leads at 0.90, followed by John Kasich at 0.89, Connie Schultz at 0.89, Claire McCaskill at 0.88, and Tim Ryan at 0.87 — a spread of only four points across five neighbors. The remaining five — Justin Amash (0.86), Bob Casey (0.86), Ken Jennings (0.86), Jason Kander (0.86), and Chasten Buttigieg (0.86) — compress even further. Seven of the ten neighbors are Politicians, matching Brown's own subcategory; the exceptions are Schultz (Journalist), Jennings (TV Personality), and Chasten Buttigieg (Professional). That the three non-politician neighbors sit comfortably inside the same narrow band as the politicians suggests the audience shape here is not strictly partisan or issue-driven — it extends into adjacent public-figure territory without a sharp drop-off. Notably, Kasich is a Republican-subcategoried politician whose audience shape lands at 0.89, nearly identical to the Democratic-aligned neighbors, which points to a cross-partisan audience composition rather than a purely ideological one.

The flat shape, with its narrow score range and predominantly same-subcategory neighbors, indicates an audience that is recognizably political in character but not tightly siloed — it overlaps broadly with other politically adjacent public figures rather than concentrating around any single one.
