Garrett County, tucked into Maryland's westernmost corner and separated from the rest of the state by mountain ridges, has delivered some of the widest Republican presidential margins in the mid-Atlantic, reflecting its rural, resource-economy roots.
The Republican margin in Garrett County reached its widest at 100 points in 1900. The margin in 2024 was fifty-four points, in line with the county's deep historical pattern.
Garrett County's loyalty is rooted in its place. Median household income of $67,688, a 95% non-Hispanic-white share, and a population of 28,615 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 Grant County and Perry County.
