Cecil County sits at Maryland's northeastern corner, culturally and politically closer to neighboring Pennsylvania and Delaware's rural precincts than to the Baltimore suburbs. Its R+30.8 presidential margin in 2024 makes it one of the state's most reliably Republican jurisdictions.
The Republican margin in Cecil County reached its widest at forty-four points in 1928. The margin in 2024 was thirty-one points, in line with the county's deep historical pattern.
Cecil County's loyalty is rooted in its place. Median household income of $92,007, a 82% non-Hispanic-white share, and a population of 104,960 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Horry County and Tioga County.
