Though the ballot for the Annandale District seat on the Fairfax County Board of Supervisors will list Democrat Sharon Bulova and Republican D. Patrick Mullins as candidates, outgoing district representative Audrey Moore may be the dominant personality in the race.

Bulova, a county board legislative aide to Moore for almost three years, is the supervisor's handpicked successor, while Mullins is relying in part on support from the business community, which has opposed Moore's slow-growth philosophy.

Moore, who gave up the seat to run against incumbent John F. Herrity for board chairman in the Nov. 3 election, became a controversial figure within the county with her early opposition to rapid development and her maverick nature, but she has enjoyed steady and strong support within her district.

Bulova makes no bones about wrapping herself in Moore's cloak -- in her literature, in interviews and on posters. Even the sign in her yard is a red and white Moore-for-chairman/Bulova-for-supervisor sign.

"I can provide the kind of continuity {Mullins} can't . . . . I am philosophically in tune with Audrey. {The voters} won't get someone with a different agenda," said Bulova, 39, who has never run for office nor worked on a political campaign.

And Mullins, who lost to Moore by a 2-to-1 margin in 1979, acknowledges that he is campaigning largely against her phantom this year.

"I think the sole strength she {Bulova} has is the coattail effect. People have told me I'm really running against Audrey again," Mullins said.

The race is the only one among the Fairfax districts with no incumbent on the ballot.

Moore expressed confidence about Bulova's election, saying she would not have run for chairman if there had not been a candidate she felt would win and carry through with the goals she had set.

But James Swinson, chairman of the Fairfax County Republican Committee, disputed that, saying the voters in the district are independent.

"I don't think Audrey Moore can put the magic touch on her {Bulova}. If Bulova's counting on that too much, she may get surprised," he said.

Mullins, 50, runs a business in his home selling insurance on horses. He is a past president of the Annandale Chamber of Commerce, the Fairfax Council of PTAs, the Wakefield Forest PTA and Frost Intermediate PTA. He said he is emphasizing this experience in community activities.

Bulova is a past president of the Kings Park West civic association and has been endorsed by the Fairfax Education Association.

Annandale is one of the county's smaller districts, with 21 square miles in the center of Fairfax County. With a 1986 population of 75,174, there were 45,668 registered voters as of last month, about 24 percent more than four years earlier.

As in other Fairfax County races this year, development and transportation are the main topics. Although Bulova wants to put the brakes on rapid development in the county, Mullins emphasizes the need for roads to accommodate increased traffic -- positions that also reflect the campaign between Moore and Herrity.

"The growth that was planned {in the 1970s} came about. There was a road network that was supposed to take care of things, but a lot didn't get built," he said. "What we didn't do over the last few years is look at what the impact of the developments was going to be" and get contributions from developers to help deal with them, he said.

"I don't think we can stop growth in the county. The tax consequences of stopping growth would be horrendous," Mullins added.

Bulova said she supports transportation improvements as well, but added that there is only so much room for roads.

"I don't think it's responsible for us to encourage growth the way we have . . . . We should shift from encouraging it to catching up with needed services," Bulova said.

One development issue that split the board last year was a proposal to curb office construction on 10,000 acres of prime land in the county and to force developers to help pay for road expansion. Bulova supports the idea, which was defeated 5-to-4 in December, while Mullins does not.

On other issues, Bulova lists child care at the top of her agenda. The county should encourage it, perhaps in connection with approval of plans for office parks, she said.

Mullins said one of his major concerns is drug and alcohol abuse among high school students. He said he wants to look at whether the county should establish substance abuse counseling centers near all the high schools.

As of the last official filing in August, Mullins had raised $18,669 in campaign contributions compared with Bulova's $7,527, which included $5,000 Bulova lent to the campaign. The Fairfax County Republican Party has put $2,800 into Mullins' campaign, and Mullins also listed contributions from the AT&T Political Action Committee of Virginia, Virginia Power, Washington Gas Light Co., and a number of Annandale businesses.

At the end of September, the Bulova campaign had more than $19,000, including the personal loan, and the campaign hoped to raise $25,000 by Election Day, according to her treasurer. Mullins declined to say how much he has raised so far, saying it might give away strategy.
