The top 10 neighbors form a tight cluster of political journalists and government officials — eight journalists and two government officials, all scoring between 0.99 and 0.98. Similarity here measures how closely two entities' audiences resemble each other in composition; the narrow band across all ten positions is the defining structural feature of this flat shape.

The eight journalists include Ashley Parker (0.99), David Fahrenthold (0.99), Susan Hennessey (0.99), Maggie Haberman (0.99), Peter Baker (0.99), David Frum (0.99), Betsy Woodruff Swan (0.99), and Robert Costa (0.99) — all fellow journalists by subcategory. The two non-journalists are Ronald Klain (0.99) and Ben Rhodes (0.99), both classified as Government Officials. No other subcategory appears in the top 10.

The absence of any spread between positions one and ten — less than 0.007 separates the highest and lowest scores — means there is no dominant neighbor pulling the audience in a single direction. Instead, the audience shape is defined by a consistent overlap with Washington-focused political journalists and senior government figures, with no outlier category breaking the pattern within these ten positions.
