Maryland's 1st congressional district

Maryland's 1st congressional district encompasses the entire Eastern Shore of Maryland, including Salisbury, as well as Harford County and parts of Baltimore County; it is the largest congressional district in the state geographically, covering all of 10 counties and part of an 11th.

The district is currently represented by Republican Andy Harris, who defeated Democratic incumbent Frank M. Kratovil Jr. in 2010. The district was the subject of a 2014 boycott following legislation Harris introduced nullifying a District of Columbia law de-criminalizing possession of marijuana. With a Cook Partisan Voting Index rating of R+8, it is the only Republican district in Maryland.
