Some big money has poured into local politics in Fairfax County over the past few days, with Board of Supervisors chairman Sharon S. Bulova (D) leading the way, the Virginia Public Access Project reported Monday evening.

Bulova, who is running against Republican challenger Michael J. “Spike” Williams, hauled in $43,140 since last Thursday, VPAP said. The non-partisan group’s latest reports cover only large donations given since Oct. 27. The election is Nov. 8, one week from today.

Among Bulova’s biggest donors was the county firefighters union – again – this time with a contribution of $10,000 on Oct. 28, the records show.

Fairfax County Professional Fire Fighters & Paramedics, which is Local 2068 of the International Association of Fire Fighters, has been the top Fairfax County donor so far this year, having contributed $78,017 to candidates for the Board of Supervisors and $5,400 to the Democratic Party of Fairfax County. Recipients on the board have included some, like Hunter Mill supervisor Catherine M. Hudgins, who have no opponents or nominal ones. Bulova alone has raked in a total of $35,417 from Fairfax’s bravest this year.

Another last-minute benefactor to Bulova’s campaign was Enviro Solutions, Inc., a Manassas-based waste hauler that emerged from Chapter 11 bankruptcy this year. The firm gave $5,000 to Bulova last week in addition to $5,000 in April.

Gary G. Nakamoto, chairman of McLean’s Base Technologies, Inc., gave Bulova $10,440 last week.

Some big checks also landed in the hands of fellow Democrat Janet S. Oleszek, a former Fairfax County School Board member who is trying to oust Republican Supervisor John C. Cook from the Board of Supervisors’ Braddock District seat.

Most of Oleszek’s help came from the Democratic Party of Virginia, which gave $19,386 in kind. Oleszek also received $1,000 from Supervisor Gerald W. Hyland (D-Mount Vernon), who is not expected to have trouble overcoming a challenge from G. Gail Parker, vice chairman of the Independent Greens of Virginia.

Unions also lent a hand, with Oleszek getting $2,500 from the United Food & Commercial Workers union and $500 from the United Auto Workers in Baltimore. She has also received endorsements from several unions, such as the county firefighters union, Fairfax Coalition of Police Local 5000, the Laborers International Union Mid-Atlantic Region, and the Fairfax Education Association.

Cook has received the endorsement of the Fairfax County Deputy Sheriffs Local 5016 and the Fairfax County Government Employees Union, which is Local 5 of the Service Employees International Union.

Other county candidates who received hefty contributions in the waning days of the campaign include Supervisor Linda Q. Smyth (D-Providence), who is facing a challenge by Republican candidate Chris Grisafe. Smyth received donations of $1,000 each from Rushmark Properties LLC and HITT Contracting.

Supervisor John W. Foust (D-Dranesville) received $500 from Catherine Rice Gorrell, who the VPAP site lists as a “homemaker/nonwage earner.”

The latest financial disclosures assembled by VPAP follow a fundraising whistle stop for Democrats by former President Bill Clinton that raised $1 million — and an triggered alarm sounded by the Fairfax County Republican Committee about the Democrats’ “money bomb.”
