Democratic mayoral nominee Sharon Pratt Dixon reported yesterday that she raised $134,106 last month for her campaign, buoyed in part by contributions from individuals and corporations that had supported some of her primary election rivals and D.C. Mayor Marion Barry.

Dixon's fund-raising was outstripped by that of her Republican rival, Maurice T. Turner Jr., who collected about $200,000 in the five-week reporting period ending Oct. 5. But Dixon reported only $23,429 in debts, compared with $177,000 for the former D.C. police chief.

Dixon reported to the D.C. Office of Campaign Finance that she had $39,232 in cash on hand, while Turner said he had $47,428.

With 25 days to go before the mayoral election, both candidates are trying energetically to raise enough money for last-minute advertising campaigns. Dixon spent the past two days in New York City, where she hoped to raise at least $100,000.

Raymond J. Howar, a GOP activist who is prominent in Washington real estate circles, hosted a fund-raiser for Turner last night that was attended by several local lawyers and Vice President Quayle.

Dixon told reporters upon returning to the District yesterday that she was unaware of the details of discussions between Barry and Washington Redskins owner Jack Kent Cooke when she said earlier in the week that she would seek to renegotiate any agreement the two reached about financing a new stadium.

In the wake of Dixon's comment, Barry announced that city officials agreed to finance a new stadium at no cost to the city.

Dixon, who during the primary campaign was the sharpest critic of the Barry administration, won financial contributions last month from earlier supporters of the mayor and some of her primary election rivals.

For example, P. Leonard Manning, an executive of the company that holds major contracts for the D.C. Lottery, had given Barry $1,000 last December, before the mayor's drug arrest. Nine days after Dixon won the Democratic primary, Manning gave her the same amount, according to campaign finance records.

The corporate entity controlling the Chicago Bar and Grill on 19th Street NW, which had given $750 each to Dixon rivals David A. Clarke and John Ray in the primary, gave Dixon $2,000 after the election.

Hardware store magnate John Hechinger, who with his wife, June, had given Dixon opponent Walter E. Fauntroy a combined $4,000 earlier this year, gave Dixon $2,000 late last month. Campaign finance records also show that the Hechingers also had given Dixon a total of $400 last fall and in May of this year.
