The top 10 neighbors for House Democrats split almost evenly between political-group peers and political news media — a composition that holds across a narrow similarity band running from 0.94 to 0.98.
The shape is flat: no single neighbor dominates. Senate Democrats (0.98) and The Democrats (0.96) are the two fellow Political Groups in the set, but they sit only a few hundredths above the media neighbors. Three TV Channels follow closely: ABC News Politics (0.96), MSNBC (0.95), and C-SPAN (0.94). Two News Publishers — CNN Politics (0.95) and NBC Politics (0.94) — round out the media cluster. The remaining three positions go to individual figures: Nancy Pelosi (0.94) as a Politician, and journalists Joy Reid (0.94) and Keith Boykin (0.94). No other subcategory appears in the top 10.
The compressed range across all ten neighbors signals an audience that tracks political institutions and political news coverage as a single, undifferentiated attention space.
