Publix's top 10 nearest neighbors split cleanly into two distinct audience neighborhoods: Florida politicians and Tampa Bay sports franchises on one side, and regional destinations and weather services on the other.

Similarity here measures how closely two entities' audiences resemble each other in composition. Rick Scott leads the set at 0.86, separated by less than 0.01 from Tampa Bay Rays (0.86) and Tampa Bay Buccaneers (0.85) — the three are effectively tied at the top. That near-tie between a politician and two sports teams is the structural signal the two-peak shape captures: Publix's audience bridges a Florida civic-and-political cluster and a Tampa Bay sports-fan cluster simultaneously.

The next tier reinforces both poles. Tampa Bay Lightning (0.82) extends the sports-team cluster — three of the top four neighbors are Tampa Bay franchises — while Busch Gardens Tampa Bay (0.82) and National Hurricane Center (0.81) anchor a second cluster of Florida-specific destinations and government services. Royal Caribbean (0.81) and Bahama Breeze (0.81) add a Florida-adjacent leisure dimension. Nikki Fried (0.79) and a second National Hurricane Center handle (0.78) round out the ten, reinforcing both the politician and the government-services threads.

No other grocery or superstore appears in the top 10. The audience shape is defined almost entirely by Florida geography — Tampa Bay sports teams, Florida politicians across party lines, and state-specific services — rather than by retail category peers.
