Fairfax County Board of Supervisors Chairman Sharon S. Bulova (D) continued to hold a commanding lead in campaign funds over her Republican challenger in the latest reporting period, according to the Virginia Public Access Project.

Bulova, who won the at-large post in February 2009 after her predecessor moved on to Congress, raised $30,829 in the Aug. 11-31 reporting period, VPAP said Tuesday. Her GOP opponent, Michael J. “Spike” Williams, raised $3,524.

Bulova has $179,722 on hand, compared with Williams’s $33,577.

The latest tally of campaign funds comes as Bulova picked up several important endorsements. On Tuesday, her campaign announced that she had received the Fairfax County League of Conservation Voters endorsement. She has also received the backing of the Fairfax County Chamber of Commerce the Fairfax Coalition of Police Local 5000, Fairfax County Professional Fire Fighters and Paramedics/IAFF Local 2068 and the Fairfax County Government Employees Union/SEIU Local 5.

In another closely watched county race, Democratic challenger Janet S. Oleszek raised $18,664 in her campaign to unseat Republican Supervisor John C. Cook (Braddock), who raised $3,536 in the August period.

Oleszek, a former Fairfax County School Board member, trails Cook with $8,868 in campaign coffers compared with Cook’s $34,754, according to the Aug. 11-31 data released by VPAP.

Oleszek’s campaign also boasted of picking up two important endorsements – from Cook’s party.

Paul E. “Red” Jenkins, who in 1991 ran unsuccessfully as the GOP’s challenger for the Braddock District then held by Bulova, is backing Oleszek, her campaign said Tuesday.

Jenkins, who taught and coached at W.T. Woodson High School, ran on the same ticket in 1991 with Thomas M. Davis, who won election as chairman of the Board of Supervisors that year, after serving as Mason District’s supervisor. Davis later became a congressman.

Tom Peterson, who taught and coached at Robinson Secondary School, has also endorsed Oleszek, said Benjamin A. Tribbett, Oleszek’s campaign chairman.

“There are few people in this community as well respected as Red Jenkins and Tom Peterson,” Oleszek said in a written statement. “I’m extremely grateful for their support, and will fight every day as Braddock District Supervisor to live up to the support I’ve received today.”
