Nine of Jonathan Karl's ten nearest neighbors by audience shape are fellow journalists — a near-total concentration within a single subcategory, with scores compressed into a tight band from 0.98 to 0.99.
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 three neighbors — Ashley Parker at 0.99, Manu Raju at 0.99, and Robert Costa at 0.99 — are all political journalists, and the scores barely separate them. Jonathan Swan (0.98), Chris Cillizza (0.98), Peter Baker (0.98), David Fahrenthold (0.98), David Frum (0.98), and Philip Rucker (0.98) round out the journalist cluster. The one departure is Ronald Klain, a Government Official, at 0.99 — sitting fourth overall, yet still within the same narrow scoring band as the journalists surrounding him.
The flat shape reflects a cluster with no dominant standout: the top neighbor leads by less than 0.01 over the tenth. What the data shows is an audience that maps almost exclusively onto the political journalism beat, with a single government-official neighbor folded seamlessly into that same audience profile.
