Tuesday's primary in southern Fairfax County will eliminate one of the six contenders for the five Democratic nominations for the 19th District seats in the Virginia House of Delegates. The district includes southern Fairfax roughly south of Rtes. 50 and 236.

The candidates are:

Gladys B. Keating, 53, of 5911 Brookview Dr. southwest of Alexandria in Fairfax County, is involved in consumer and civic activities as a volunteer. She has attended Queens College in New York, Weatherford College in Texas and the University of Virginia and George Mason University. She has previously sought the seat in 1973 and 1975, narrowly losing the nomination two years ago.

Keating lists her personal legislative objectives in the upcoming session as:

"1. Development and implementation of a well-balanced transportation system.

"2. Development of a comprehensive energy research and conservation program.

"3. Better legislative oversight of utilities.

"4. Legal recognition of the wife's contribution to marriage (both the working and the homemaker).

"5. Complete overhaul of the tax structure.

"6. Implementation of the Government Management Commission recommendations, as well as reformation of the legislative process itself."

Michael Patrick Leahy, 22, of 8601 Raleigh Avenue, Annandale, is a veteran attending Northern Virginia Community College on the G.I. Bill.He has not previously sought public office.

Leahy lists his personal legislative objectives as:

"I desire a moratorium on the development of atomic energy for electrical power in Virginia until such a time as the industry, at its own expense, devises a method of accelerating the decomposition of nuclear wastes.

"I understand VEPCO gets a tax deduction for construction of electrical energy generating facilities (and) this is the first loophole I would like to do away with.

"I feel there are too many people in Virginia prisons who never committed a violent or larcenous and too many people not in Virginia prisons who did. I consider the possessor (for use) of an illegal drug to be a victim, not a criminal, and would seek the replacement of prison sentences with fines, a deterrent for marijuana users.

"In the event the prison population exceeds 95 per cent of the planned capacity, it becomes necessary to weed out drug victims, sex offenders and other non-violent, non-larcenous inmates (so) they can be placed in programs outside prison walls where they can serve their debt to society without fear of sodomization, extortion and physical abuse from fellow inmates."

"PCP needs to be upgraded on the list of dangerous drugs. I do not feel the letter "A" should be tattooed onto the forehead of a PCP dealer prior to his being thrown into a windowless cell. The reason I would not approve such action is the Supreme Court would overthrow it as 'cruel and unusual.' Nevertheless, there must be something constitutional we can do along the same lines."

Thomas Jefferson Rothrock, 44, of 10602 Windermere Lane, Fairfax Station, is an attorney seeking his fourth consecutive term in the Virginia House of Delegates. He was graduated from the University of Maryland and the George Washington University Law School.
