The top 10 neighbors for Sen. Marsha Blackburn span a narrow similarity band — from 0.96 down to 0.93 — with no single dominant neighbor and no sharp drop-off between them. That flat distribution is itself the structural finding: this audience does not concentrate around one anchor; it spreads evenly across a dense cluster.
Subcategory composition tells the story clearly. Six of the ten neighbors are Politicians: Mike Huckabee (0.96), Mike Pence (0.95), Donald Trump Jr. (0.94), Rand Paul (0.94), Eric Trump (0.94), and Ben Carson (0.93). The remaining four break into adjacent subcategories: FOX & Friends (0.94) is a TV Show, Sarah Huckabee Sanders (0.94) is a Government Official, Sean Hannity (0.93) is a TV Personality, and Trey Gowdy (0.93) is also a Politician — making seven Politicians total in the top 10. The non-politician entries are all political-media adjacent: a morning news program and a prime-time TV personality, both within the same ideological media ecosystem as the politician neighbors.
No athletes, entertainers, or brand accounts appear in the top 10. The audience shape here is almost entirely same-kind — politicians and political media — with scores compressed tightly enough that no single neighbor stands meaningfully apart from the rest.
This is a highly consolidated audience that tracks a specific political-media world with little diffusion into other content categories.
