Republicans in Fairfax County's Providence District will hold a canvass today to select the GOP nominee to run for the Board of Supervisors in a special election July 15.

Bob Beers, a former aide to Supervisor Thomas M. Davis III (R-Mason), and State Del. Stephen E. Gordy (R-Fairfax), a retired Army colonel and public school principal, are seeking the Republican nomination.

The winner will face Providence District School Board member Kate Hanley, a Democrat, in the special election. Hanley has no Democratic challenger.

The special election was set after Supervisor James M. Scott, a Democrat, announced this month he will resign from the County Board June 3 to become director of community relations at the Fairfax Hospital Association. Scott has served on the nine-member board for nearly 15 years.

The winner of the special election July 15 will represent Providence District, an oddly shaped area comprising about 85,000 people and stretching from the Arlington County line to Western Fairfax County. The district includes Tysons Corner and Fair Oaks Mall, as well as the new Vienna and Dunn Loring Metro rail stations.

Polls are open today from 4 to 9 p.m. at Marshall High School, 7731 Leesburg Pike.

The contest today is expected to be decided almost entirely on organizational factors. Beers and Gordy have not disagreed on any substantial issues; rather, each has touted his ability to win in the special election.
