Beltway battle lines

Mapping Nationals-Orioles fandom

By Lazaro Gamio and Laris Karklis, Published: Sept. 20, 2014

Data provided by Facebook on the distribution of “likes” for the Nationals and Orioles hints at where fan allegiance for the teams divides geographically. The Nationals base is dominant in Virginia and the District, while the Orioles own nearly all of Maryland. The Nationals influence spreads into Maryland only along the Capital Beltway and I-270 in Montgomery County and south of Route 50 in Prince George’s County.
