The name of a Washington attorney, Karen Hastie Williams, was spelled incorrectly yesterday.

Mayor Marion Barry, still irritated with a City Council committee's rejection of Sterling Tucker to head the D.C. Board of Elections and Ethics, said yesterday he hopes to submit a new nominee by tomorrow.

At his regular monthly press conference, Barry also said he favors postponing this year's 367 Advisory Neighborhood Commission elections, defended his support of minority contracting and downplayed as political rhetoric the concerns in Fairfax County over security at the Lorton prison complex.

City government officials said yesterday that Clifford L. Alexander Jr., who was secretary of the Army under President Carter and an unsuccessful candidate for mayor in 1974, is a leading candidate for the chairman of the board of elections.

Alexander, now in private practice, was in Philadelphia yesterday and could not be reached for comment.

Another prominent local attorney, Karen Hasty Williams, turned down the job because of a potential conflict of interest with corporate clients of her firm, Crowell and Moring.

Although Barry has all but ruled out resubmitting Tucker's name, the mayor said he asked the former chairman of the council "to think about whether or not he wants to subject himself to this abuse . . . . "

A council committee, acting without public notice, rejected Tucker's nomination last week after efforts to get Barry to withdraw the name failed. Barry said the vote by the committee on government operations "impugned the character and integrity" of Tucker.

Barry is expected to resubmit the name of Valerie K. Burden to fill a second vacancy on the three-member board. Burden also was rejected in the committee's action last week, but council members said there was no real opposition to her.

On postponing elections, Barry said the council does not have time to complete a required redistricting of the 367 ANC single member districts before November. The ANC members, who represent about 2,000 persons, are elected to pursue neighborhood concerns.

In addition, Barry said the elections board can't complete a redistricting of precinct boundaries before November. The mayor said he supports a plan to align the ANC and precinct boundaries so that no individual ANC single member district crosses a precinct boundary--a situation that now creates confusion at the polls.

Barry said he has not yet decided whether to support postponing school board elections this year to give the elections office time to hire a new executive director and end administrative chaos that has marred the city's elections system.

That plan, which had early support on the council, is likely to be rejected in favor of a compromise to hold the school elections but put off the ANC balloting until next year.

Meanwhile yesterday, current elections board chairman Albert J. Beveridge III said his office has completed a new list of 149,030 names of individuals who voted in the September primaries and November general election last year.

The list, which will be placed in the King library downtown Friday and branch offices late next week, may be used as a base registration list for future voting. If the council agrees, persons who did not vote last year would have to reregister.

At his news conference, Barry adamantly rejected any suggestion that he has interfered to favor friends in the city's contracting programs.

"I'm not an investor in any of these companies," Barry said in response to a reporter's question. "I don't favor anything but good government, good contracts . . . . I don't favor one or two minorities in this city getting rich at the expense of others . . . . I'm philosophically committed to spreading the wealth of this community around, among all of its people, and I'm going to make sure it gets done. . ."

Barry, who toured the Lorton prison complex last week with Fairfax officials, said the city is doing everything it can to maintain or improve security there.

"There are some legitimate concerns about security," Barry said, adding, "I think we've met those concerns." The mayor noted all nine of the Fairfax supervisors are up for election this year. "I'm sure the rhetoric is going to heat up even more . . . . the reality of life is that Lorton is going to be there."

On another issue, Barry all but took himself out of the speculation on whether to seek the Democratic nomination for president to unite black voters, a move suggested by several black leaders who feel the national party has taken blacks for granted. Barry said he is too busy being mayor.

Barry also said he will announce a new anticrime program soon, but declined to reveal details yesterday. "We are going to announce some new thrusts. It's getting springtime. You have to have a spring offensive."
