Maryland was a one-party state, like others in the South, until after the passage of civil rights legislation in the mid-1960s to protect the right to vote. No Republican carried Wicomico County until 1928, when Herbert Hoover won due to anti-Catholic sentiment in the heavily Protestant county against Democratic candidate Al Smith. The popular general Dwight D. Eisenhower carried Wicomico in 1952. Since the late 20th century, white conservatives, the majority in the county, have increasingly joined the Republican Party. In this same period, African-American voters have tended to favor the Democratic Party.
