Jennifer Rubin's nearest audiences are a mix of politicians, academics, government officials, and journalists — with no single subcategory dominating the top 10. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 1.0 indicates near-identical audience shape.
The top 10 span a tight band from 0.98 to 0.99, consistent with the flat shape classification. Neal Katyal (0.99) and Laurence Tribe (0.99) represent the Academics subcategory; George Conway (0.99), Bill Kristol (0.99), and Rick Wilson (0.99) are classified as Politicians; John O. Brennan (0.99) and Steve Schmidt (0.98) round out the non-journalist contingent as Government Officials and Professionals respectively. Only three neighbors share Rubin's own Journalists subcategory: Natasha Bertrand (0.98), Matthew Miller (0.98), and Nicolle Wallace (0.98). The dominant pattern is cross-kind: seven of the ten nearest neighbors are not journalists, drawn instead from legal, political, and government-adjacent figures. No single neighbor pulls away from the pack — the scores compress into a 0.013-point range — which means the audience shape is defined less by one anchor than by a consistent cluster of politically oriented, institutionally credentialed voices.
This flat, cross-kind structure suggests Rubin's audience is shaped primarily by political and legal commentary rather than by journalism as a craft category.
