The fund-raising spigots have been turned wide open for Democratic mayoral nominee Sharon Pratt Dixon, who could barely raise enough money to keep her long-shot primary campaign afloat.

Dixon raised $414,147 in contributions during the last three weeks, almost twice the amount she raised in the previous year and a half of campaigning, according to finance reports released yesterday.

With a week to go before the general election, Dixon has pulled far ahead of Republican nominee Maurice T. Turner Jr., reporting a total of $699,532 in contributions.

Turner, who raised $61,670 during the latest reporting period, has raised a total of $555,555 for his campaign. However, he has had to borrow $150,000 to help finance his campaign.

Perhaps most significant, Dixon is now flush with money for the first time in her campaign, reporting $296,449 in cash on hand as she prepares for a last-minute television and radio blitz.

She reported campaign debts of $6,732.

Turner reported $65,121 in cash on hand and $182,690 in campaign debts and obligations, up slightly from three week ago.

Mayor Marion Barry also did well in fund-raising for his bid for an at-large D.C. Council seat, raising $60,352 during the last 18 days, for a total of $95,372. He reported cash on hand of $67,244.

Barry received numerous contributions from current or former city officials, including $200 from N. Anthony Calhoun, director of the Department of Human Services; $100 from Deputy Mayor Wylie L. Williams Jr.; $100 from public housing chief Roland L. Turpin; and $100 from Deputy Mayor Robert Pohlman. He also received $200 from D.C. Council member H.R. Crawford (D-Ward 7).

Barry outdistanced several rivals in fund-raising, including Democrat Linda W. Cropp, who raised $20,991 in the period; council member Hilda H.M. Mason, who raised $16,859; Jim Harvey, who raised $2,597; Clarene Martin, who raised $4,915; and Ray Browne, who raised $394.

Dixon received money from a cross section of the business community, including lawyers, developers, the political action committees of Washington Gas Light and Potomac Electric Power Co., and securities firms. She received contributions from numerous former supporters of Barry and other mayoral candidates.

She received $1,000 from restaurateur Jeffrey Gildenhorn; $1,000 from construction executive Carroll Harvey; $1,000 from public relations executive Jeanne C. Harris; $750 from developer S. Jon Gerstenfeld; $2,000 from Wardell Lazard, one of the city's finance advisers; $1,300 from developer Gerald Lustine; and $1,000 from developer Bahman Batmanghelidg.

She received $5,000 from companies associated with Black Entertainment Television, headed by former Barry adviser Robert L. Johnson.
