The top 10 neighbors in Maureen Dowd's similarity graph are overwhelmingly journalists and authors — a tight cluster of political media figures with no standout outlier pulling the shape in any unexpected direction. Similarity here measures how closely two entities' audiences resemble each other in composition; scores across the top 10 run from 0.97 to 0.98, a band narrow enough that no single neighbor dominates.

Seven of the ten are fellow journalists: Philip Rucker (0.98), Peter Baker (0.97), Andrew Ross Sorkin (0.97), Michael S. Schmidt (0.97), Jim Sciutto (0.97), Maggie Haberman (0.97), and David Frum (0.97). Two more — Thomas L. Friedman (0.98, the highest score in the set) and Frank Bruni (0.97) — are classified as Authors, not Journalists, though both operate squarely in political commentary. The one departure from that pattern is Andy Borowitz (0.97), a Comedian, whose audience shape nonetheless sits comfortably inside this cluster. The scores compress into a 0.012-point range across all ten, which is the defining structural feature: no single neighbor stands apart, and no category outside political media and commentary breaks through in the top 10.

This is an audience shaped almost entirely by Washington-focused political journalism, with essentially no separation between the nearest neighbors.
