Susan Collins's top 10 neighbors span a narrow similarity band — 0.90 down to 0.88 — with no single standout and no dominant cluster pulling in one direction. The shape is flat: the audience that follows Collins distributes its attention across a mix of subcategories rather than concentrating around any one type.
The composition of those 10 neighbors is the finding. TV personalities make up the largest single group: Mimi Rocah (0.89), Jill Wine-Banks (0.89), and Glenn Kirschner (0.89) all land in the top 10. Government officials are the next cluster: Barb McQuade (0.90) and John O. Brennan (0.88). Only two fellow politicians appear — Sen. Lisa Murkowski at 0.90, the highest score in the set, and John Dean at 0.89. The remaining three positions go to a journalist (Joyce Alene, 0.90), an academic (Richard W. Painter, 0.89), and a professional (Dr. Dena Grayson, 0.88). Across the full top 10, politicians are a minority — the audience shape is defined more by legal commentators, intelligence-community figures, and TV news personalities than by elected officials.
This flat, cross-kind pattern suggests an audience organized around a particular political moment and media ecosystem rather than around the center entity's own institutional role.
