Hough is finishing his first term in the House of Delegates. Hough campaigned as the more conservative candidate.
On the Eastern Shore, Del. Adelaide Eckardt defeated Sen. Richard Colburn in a district that includes Talbot County, as well as parts of Dorchester, Caroline and Wicomico counties.
Colburn has held the seat since 1995. Eckardt has served in the House for the same period.
