Incumbent Del. John P. Donoghue defeated former state legislator Paul D. Muldowney in the Democratic primary for the District 2C seat in Tuesday's primary election.
Donoghue received 1,385 votes to Muldowney's 1,091, according to complete but unofficial results.
"I'm very proud of the campaign I ran. I'm very proud of my record over the past eight years and I'm looking forward to serving the citizens of Hagerstown over the next four years," Donoghue said after the results were tallied.
With no Republican opposition in the district, the Democratic primary victory virtually guarantees Donoghue will retain his General Assembly seat.
Muldowney had no comment following the results, according to a woman who answered the telephone at his home and identified herself as a friend of the family.
Muldowney, 63, a Hagerstown resident, served in the House of Delegates from 1979 to 1986 before losing to current Del. D. Bruce Poole, D-Washington, in a Democratic primary. He has since run unsuccessful campaigns for the state Senate and the U.S. House of Representatives.
