A group of seven Democrats, including four incumbents, said yesterday they are running on a slate for the Montgomery County Council.

Joining the incumbents -- Rose Crenca, Michael Gudis, William E. Hanna Jr. and Neal Potter -- are candidates Bruce Adams, Isiah (Ike) Leggett and Michael Subin.

An obvious omission from the slate is Jay Bernstein, chairman of the county Democratic Central Committee, who is also campaigning for a council seat and who county politicians said had asked to be part of the group. "It's not a snub to anybody," said Adams, a Bethesda resident who has served as research director of Common Cause and a fellow of the Kennedy Institute of Politics at Harvard University.

When asked why the candidates chose Subin -- a former Republican who is the only candidate in the slate from the upper county -- rather than Bernstein, Adams said, "I think one factor is that Subin is from Gaithersburg and the fast-growing, up-county areas have not been represented. We preferred Subin on the grounds of geographical balance and issue orientation because of his involvement on community boards and issues that are pretty impressive."

Subin has served as vice president for legislative affairs of the Montgomery County Chamber of Commerce and as chairman of the Committee for the Upcounty.

If Leggett, assistant dean at the Howard University Law School, is elected, he would be the first black to serve on the County Council. He has served as chairman of the county Human Relations Commission.

The slate does not include a candidate for executive. "We're not having an executive candidate on the slate because it could pit friends against each other," Hanna said at a news conference to announce the slate. The three Democratic candidates for the seat are council member David Scull, state Sen. Sidney Kramer and Department of Recreation head David Robbins.

Kramer had tried to entice most of the candidates on the slate to join him on a ticket, but his intense efforts failed in early March, according to Kramer supporters.

Running on a slate is less expensive and more efficient, said Hanna. The group hopes to raise at least $100,000. "It's the only reasonable way to run in this county," he said.
