The top 10 neighbors for AP Politics span five distinct subcategories — no single kind dominates, and the scores compress into a narrow 0.97–0.96 band — a textbook flat shape where the audience's composition, not any one standout, is the real finding.
Similarity here measures how closely two entities' audiences resemble each other in composition. The nearest neighbor is AP Stylebook at 0.97, a fellow News Publisher. After that, the cluster diversifies immediately: Serial (0.96) and Crooked Media (0.96) are Podcasts and Radio; Merriam-Webster (0.96) is a Website; SCOTUSblog (0.96) is a Blog; Ari Shapiro (0.96) and Tamara Keith (0.96) are Journalists; 538 Politics (0.96) is a Blog; Pew Research Center (0.96) is a Research Organization; and Pod Save America (0.96) rounds out the ten as another Podcasts and Radio entry.
Tallying the subcategories: Podcasts and Radio accounts for three neighbors, Blogs for two, Journalists for two, with News Publishers, Websites, and Research Organizations each contributing one. AP Politics itself is a News Publisher, making AP Stylebook the only fellow News Publisher in the top 10. The cross-kind character of the cluster — heavy on podcasts, political blogs, and individual journalists rather than other news publishers — defines the shape more than any single neighbor does.
The flat, multi-subcategory spread suggests an audience that moves fluidly across text, audio, and data-driven political content rather than anchoring to any one format.
