Del. Constance A. Morella, a Republican candidate for Congress in the 8th District, plans a "people-to-people" campaign that she says will take her to thousands of doorsteps from Gaithersburg to Silver Spring.

Morella planned the near-daily walks to meet voters from one end of the congressional district to the other, starting May 12 at the North Creek Community Center in Montgomery Village. Her hikes later will take her to neighborhoods and business districts in Gaithersburg, Rockville, Wheaton and Silver Spring. She also plans to knock on doors in Olney, Bethesda and Colesville.

A spokesman for Morella said the street-level campaign will continue at least until the Republican primary in September, which pits Morella against retired Foreign Service officer William S. Shepard.

Meanwhile, Esther P. Gelman, a Democrat running for Congress in the same district, took her campaign to 6,000 Montgomery County employes last week by putting a little something extra in their paychecks.

Gelman, a County Council member who heads the council's personnel committee, wrote a brief "alert" about legislation pending in Congress that would eliminate certain tax benefits on pension payments.

Gelman's message, which was included in county employes' pay envelopes last Friday, raised more than a few eyebrows in the office of the County Executive, who theoretically oversees such things. Several key officials said they had no prior knowledge that the election-year notice was being distributed to county employes.

Zoe Lefkowitz, Gelman's aide, said the council member has issued only one other such notice, a flyer last August asking for employe suggestions on medical insurance forms. Walker Backs His Contributions

Nine days after the brutal murder of Sophie C. Glukenhous, an 85-year-old Silver Spring resident, politician DeVance Walker Jr. issued a press release decrying the slaying and reiterating "his support of the issues and concerns facing the elderly population" of the area.

Walker, an aide to County Executive Charles W. Gilchrist, is running for a seat in the House of Delegates in 20th Legislative District, which includes Silver Spring. Police have not captured Mrs. Glukenhous' assailant.

Walker donated $200 to Crime Solvers Inc. to encourage witnesses to come forward with any information about the murder. He included a photostat of his check in his mailing to reporters. Not-So-Sweet Revenge

Political revenge can be sweet or subtle, but in the case of Montgomery County Council member Neal Potter, it also can be neither.

Potter, still seething over the council's defeat in Annapolis over a series of planning bills sponsored by County Executive Charles W. Gilchrist, wants to strip Gilchrist's staff of -- you guessed it -- two Annapolis lobbyists.

At an April 17 meeting with several Gilchrist aides, Potter complained about the "5-to-1 disadvantage" that the council suffers because of its limited lobbying staff, according to minutes of the meeting.

Potter then called for the transfer of two lobbyist positions from executive control to council control, a move of dubious legality given the strict prohibition against such maneuvers in the law affecting the county government's budget.

As council member Rose Crenca noted at the meeting, stripping the executive of two lobbyists just might leave the impression that the council was "angry at the executive and was taking action against him." Announcements
