The only woman and one of the longest serving members of the Prince William Board of County Supervisors will seek reelection in November.

On Sunday, about 140 supporters helped Maureen Caddigan (R-Dumfries) kick off her campaign at Giorgio’s in Lake Ridge. Caddigan has held the seat since 1991, and only Supervisor John D. Jenkins (D-Neabsco) has served on the board longer.

“I really like my job and believe I have made a difference over the years,” Caddigan said. “I think I have accomplished a lot, but I have a lot more I want to do.”

Caddigan, who is running unopposed, said she will remain committed to education, public safety, transportation, economic development and low taxes. If reelected, she also wants to ensure the Harbor Station development becomes a reality.

The proposed town center development has sat idle during tough economic times, but Caddigan said they are working on bringing a new developer in to revitalize the project. Harbor Station was in the Woodbridge District until the redistricting process shifted it into Caddigan’s Dumfries — soon to be Potomac — District.

Before joining the board, Caddigan spent seven years on the Prince William School Board. As a supervisor, she led efforts to bring the National Museum of the Marine Corps to the county and to widen Route 1 through Dumfries. She represents the county on numerous boards, including the Virginia Railway Express, and has been appointed by several governors to serve on Virginia commissions.

Caddigan is one of seven people seeking reelection to the county board. Supervisor John T. Stirrup (R-Gainesville) has decided to run for a newly created state Senate seat that includes part of Prince William.

With Stirrup out of the competition, several Republicans and one Democrat are looking to take his seat. Republicans Steve Botello, Suzanne Miller, Peter Candland, Martha Hendley and Michael High have all filed their intentions with the county’s registrar, along with Democrat Ann Wheeler.

Supervisors W.S. Covington III (R-Brentsville) and Martin E. Nohe (R-Coles) also have challengers. Covington will face Jeanine Lawson in the Aug. 23 Republican primary while Nohe will face J. Robert Pugh Jr.

Board Chairman Corey A. Stewart might face a fellow Republican, Haymarket Town Council member Robert B. “Bob” Weir, in the primary. Independent John Gray and Democrat Babur Lateef are also vying for the seat.
