The top 10 neighbors for Senator Jeff Merkley are dominated by journalists, with six of the ten slots occupied by that subcategory — and the scores across all ten sit within a tight 0.95–0.94 band, confirming the flat shape.

Kurt Eichenwald (0.95), David Corn (0.95), and Kyle Griffin (0.95) lead the set, separated from one another by less than 0.001 — effectively tied. Dr. emptywheel (0.95), Natasha Bertrand (0.95), and Charles P. Pierce (0.94) round out the journalist cluster. The remaining four neighbors are drawn from distinct subcategories: Sierra Club (0.95) as an Environmental organization, Brennan Center (0.94) as a Non-Profit, Molly Jong-Fast (0.94) as an Author, and Adam Parkhomenko (0.95) as the lone fellow Politician in the top 10. Merkley's own subcategory — Politicians — appears only once among the ten neighbors, meaning the audience shape is defined far more by political journalism and adjacent civic media than by other elected officials.

The flat distribution across a narrow similarity range suggests this audience is cohesive and consistent, with no single neighbor pulling significantly harder than the rest.
