Dottie-O, Wesigo's Last and Dawne, Lightning made D.C. City Council member Willie J. Hardy a $1,068 winner at Laurel Race Course last year - on the same day that a special citizens committee was scheduled to consider whether gambling should be made legal in the District.

"I won this. I'm very proud of it. I even gave them my social security number," said Hardy, who also won $1,312 at the Shenandoah Downs-Charles Town Turf Club complex last year on a trip she said was sponsored by a local church.

Hardy refused to name the church. "That would hurt (me on the gambling issue with the church (voters)," she said, "and the churches are supporting me (politically)."

When Hardy was then reminded that one group of prominent black Baptist ministers has voiced strong opposition to gambling in general and legal gambling in Washington in particular, she replied, "They don't represent all the ministers, honey."

Hardy said she plans to go to the race track with another church next month. She said she has talked to one churchman recently about her trips and was quoted a passage from the Bible about a woman in a similar situation of supposed quilt.

"It's the one where they said, Let he who is without guilt cast the first stone,' and couldn't a soul throw a stone," Hardy said.

Hardy listed the $2,380 in race track earnings as part of her 1977 income on the financial disclosure report she filed this week with the D.C. Board of Elections and Ethnics.

City lay requires all 25 local elected officials, plus an estimated 4,000 other city employes to file such forms as a deterrent to possible conflicts of interest. Only forms field by the elected officials are open to the public, however.

The racing income and $450 received beyond her Council salary of nearly $27,000. She listed $71,600 in assets and $26,000 in liabilities.

Officials at Shenandoah said Hardy was a "regular" at the track who came up with groups carried by a Washington-based limousine service. But Hardy said she had been to the horse races only 10 or 12 times in her life.

Reports from other city officials displayed a wide variety of incomes and implicit life styles, but none appeared to be in positions of potential conflict of interest. Not all of the reports were commuted in the same way, and in some cases joint assets, liabilities, taxes and salaries were included.

Following are highlights of some of the reports:

Mayor Walter E. Washington, who reported assets of $104,00 (jointly held with his wife) and liabilities of $1,400, has $72,000 in cash on hand in the form of savings and checking account balances. Since 1975, the mayor, whose annual salary is more than 50,000, has had a cash balance in excess of $50,000. A mayoral spokesman would not elaborate on it.

City Council Chairman Sterling Tucker had assets of $163,100 and liabilities of $55,477 - primarily mortgage payments. Tucker purchased $6,000 additional interest last year in Washington Community Broadcasting Co., which recently gained control of radio station VYAN.

City Council member Marion Barry (D-At large) has assets of $14,016 and liabilities of $1,635, nearly all of which was outstanding balances on credit card and charge accounts.

Barry reported receiving more than $2,300 in local and federal income tax refunds last year.

Council member Hilda Mason (S-At large received no income last year other than her Council salary of about $27,000, but along with her husband a wealthy retired government employe, paid $31,402 in federal income taxes. Mason has no liabilities and listed $78,882 in assets, chiefly through her ownership in her home in Northwest Washington and land in Vermont.

Council member Jerry A. Moore, (R-At large) reported assets of $88,000 and liabilities of $5,000.In addition to his council salary, he received $11,750 in salary as pastor of 19th Street Baptist Church. Moore also reported dividends from holdings in utility companies.

David A. Clarke (D-One) had assets of $104,073 and liabilities of $88,892. Clarke reported spending $45,000 to purchase a house that is now worth about $60,000. Clarke points out, however, that the house, which he rents out cost another $21,000 to renovate.
