Patricia Roberts Harris raised a total of $642,451 for her unsuccessful campaign for mayor, about half the amount raised so far by Mayor Marion Barry, according to a campaign finance report filed yesterday.

The report said Harris ended her bid for the Democratic mayoral nomination with a $22,133 debt. Sharon Pratt Dixon, Harris' campaign director, said yesterday that much of the debt covers administrative overhead.

Dixon said the campaign deferred payment of several administrative costs in the final days of the campaign so money could be spent on a last-minute advertising and media blitz "in an effort to keep up with the advertising behavior of the competition."

Barry's latest campaign finance statement said he has raised a record total of $1.2 million so far -- $235,726 between Aug. 21 and Oct. 7 -- and spent $807,873 on media and other expenses. Abramson Associates, the Washington firm that handled much of Barry's advertising, received payments totaling $93,411 for media and research services in the final weeks of the campaign, the report said.

Dixon said Harris plans to pay off her debt by holding fund-raisers in the coming weeks. She said several supporters who have contributed less than the $2,000 maximum contribution have offered to make additional donations to pay off the campaign debt, and that developer Oliver T. Carr and attorney Henry Hubschman are spearheading the fund-raising effort.

A number of the donations to the Barry campaign between Aug. 21 and Oct. 7 were "in-kind contributions" of food, apparently for Barry fund-raisers, from several private citizens and city restaurants and carry-outs.

Barry's report lists a $1,000 in-kind contribution for refreshments from parking lot owner and real estate developer Dominic F. Antonelli Jr.; a $100 contribution of food from Department of Recreation Director William H. Rumsey; $130 in supplies from former Department of Human Services Director Joseph P. Yeldell, and $80 for food from Yeldell's wife, Gladys.

Barry also reported spending $107,600 on salaries for some 200 campaign workers through Oct. 7.

The four candidates for the Ward 3 City Council seat also filed campaign finance reports yesterday. Incumbent Polly Shackleton, who won the Democratic nomination, reported raising $34,157 so far.

Former League of Women Voters President Ruth Dixon, who came in second in that race, raised $28,245 and political consultant Mark Plotkin reported $23,378 in contributions.

Ward 3 Republican candidate Lois DeVecchio, who ran unopposed in the primary, reported raising $10,297 for her campaign through Oct. 6, including $500 from Joseph and Holly Coors of the Coors beer family.

W. Ronald Evans, the Republican candidate in Ward 5, reported raising $2,385 so far.

School board member Frank Smith Jr., who won the Democratic nomination for the Ward 1 City Council seat, reported $24,772 in contributions so far, while Maurice Jackson, an independent candidate for council in Ward 1, reported raising $2,553 so far.

Ward 6 Council member Nadine Winter, who won the Democratic nomination in that ward, raised $37,799 through Oct. 10, including a $400 contribution from GEICO, the Government Employes Insurance Co. Winter was a co-sponsor of a no-fault auto insurance bill backed by GEICO.

Council member Hilda Mason (Statehood-At-Large) reported raising $1,275 for her reelection campaign so far, $1,000 of which she loaned to her campaign. She and Council member Betty Ann Kane (D-At-Large) are running unopposed for two at-large seats.

Glenn White, a Socialist Workers Party candidate for mayor, reported $1,172 in contributions through Oct. 10.
