Anita Bonds, who held key posts in Mayor Marion Barry's two previous mayoral campaigns and who directed constituent services for the mayor, will manage his bid for a third term this year, Barry has announced.

Although Barry has not formally launched his reelection campaign, he introduced Bonds as his choice for campaign manager at a Monday night reception held by the Gertrude Stein Democratic Club, a gay rights group that endorsed him for another term.

Bonds, 40, was deputy campaign manager in Barry's 1978 and 1982 mayoral campaigns. She has worked on the presidential campaigns of Sen. Edward M. Kennedy (D-Mass.), the Rev. Jesse L. Jackson and former vice president Walter F. Mondale.

Bonds, now special assistant to the director of the D.C. Department of Housing and Community Development, has been in and out of city government throughout Barry's two terms, dealing primarily with constituent services. In 1983, as director of the D.C. Office of Community Services, she organized volunteers to deal with complaints about city services, which some critics claimed constituted a taxpayer-financed campaign organization.

No substantial opposition to Barry has surfaced. There have been hints that City Council Chairman David A. Clarke is considering entering the race; he has not announced any decision.

Neither of the two announced candidates for mayor is well known or holds office.

Mattie Taylor, a former D.C. school board member and retired D.C. Employment Services deputy director, has formed a campaign committee and plans to make a formal announcement on Saturday.

Dennis Sobin, a publisher of sexually oriented newspapers, announced last week that he is running for mayor for the second time.

Ann Heuer, chairman of the D.C. Republicans, said that her party has not put up a candidate for mayor and that she did not know whether it will do so.

But Bonds said yesterday that Barry would wage "an aggressive campaign" regardless of the opposition. "Each time the candidate runs he must reestablish his relationship with the voters," she said. "They want to know his platform."

In 1982, Barry faced substantial opposition in the Democratic primary from Patricia Roberts Harris, a Carter administration cabinet member who has since died. In addition, City Council members John A. Wilson (D-Ward 2), Charlene Drew Jarvis (D-Ward 4), John Ray (D-At Large) and Betty Ann Kane (D-At Large) entered the race that year, although Kane and Wilson dropped out before the Democratic primary.

Barry's campaign manager in 1978 and 1982 was Ivanhoe Donaldson, who recently pleaded guilty to charges of fraudulently obtaining more than $190,000 from the city government from 1981 to 1983.
