Nancy R. Stocksdale, an aide to Rep. Roscoe G. Bartlett, has announced she is running for a 5th District delegate seat later this year.
Mrs. Stocksdale, a retired teacher who lives in Westminster, is the fifth Republican to run for the seat. Three Democrats also have announced their candidacies.
As a result of redistricting in 1991, Carroll's 5th District will gain a third delegate seat next year.
Other Republicans who plan to run in September's primary are W. David Blair of Manchester, Jerome J. Joyce of Hampstead, Joseph H. Mettle of Eldersburg and incumbent Richard C. Matthews of Hampstead.
Democrats who have announced their candidacy are incumbent Richard N. Dixon; Ellen Leahy Willis of Westminster, who finished third in the 1990 general election; and Philip R. Deitchman of Eldersburg.
The top three vote-getters from each party in the primary will advance to the November general election.
Mrs. Stocksdale, 59, has been active in local politics for 11 years. She was elected to the Carroll County Republican Central Committee in 1990 and is president of the Carroll County Republican Women's Club and past president of the Carroll County Republican Club. She also was an alternate delegate to the 1992 Republican National Convention.
Mrs. Stocksdale has worked as a district assistant for Mr. Bartlett, a Republican who represents Maryland's 6th District, since she retired from the Baltimore County public schools in January 1993.
She taught home economics in middle and high schools for more than 34 years.
As a congressional aide, she helps constituents solve problems related to the federal bureaucracy and accompanies Mr. Bartlett on his visits to the district.
Mr. Bartlett's spokeswoman, Cheri Jacobus, had no comment yesterday on Mrs. Stocksdale's candidacy.
Mrs. Stocksdale said that she has heard many people say that someone should try to solve problems with crime and education.
"Everybody says somebody ought to do something about it. I decided I would do that, I would run," she said.
Mrs. Stocksdale said she would oppose tax increases and would introduce legislation that would require convicted criminals to serve at least 50 percent of their sentences.
She also advocates giving tougher sentences to persons convicted of using guns while committing crimes.
"Today, it seems that the criminal has the freedom to roam the streets while the law-abiding citizens must keep themselves locked in their homes," she said.
Mrs. Stocksdale, a widow, has five children and three grandchildren.
