Mark Warner's top 10 neighbors span journalists, politicians, government officials, and academics — with no single neighbor pulling far ahead of the rest. Similarity here measures how closely two entities' audiences resemble each other in composition; the scores across Warner's top 10 run from 0.94 down to 0.90, a notably compressed band.

The shape is flat. Larry Sabato (0.94, Academics) sits at the top, followed closely by fellow politician Tim Kaine (0.93) — the only other Politician in the top 10 alongside Warner's own subcategory. From there, the cluster is dominated by Journalists: Chris Cillizza (0.91), Manu Raju (0.91), Kaitlan Collins (0.91), Dana Bash (0.91), and Jonathan Karl (0.90) all land within a few hundredths of each other. Rounding out the ten are two Government Officials — Doug Emhoff (0.90) and Secretary Antony Blinken (0.90) — and Chuck Todd (0.90), another Journalist. By subcategory count, five of the top 10 are Journalists, two are Government Officials, one is an Academic, one is a fellow Politician, and one is a Journalist/host. The cross-kind finding is the dominant signal: Warner's audience shape aligns more tightly with political journalists and government officials than with other politicians.

The compressed score range and journalist-heavy neighbor set together suggest an audience defined less by partisan affiliation than by sustained, close-range attention to Washington process and coverage.
