Vienna-area voters choosing a Republican ballot Tuesday, Aug. 4, will pick from two contested primaries: a three-way race for the party's U.S. House nominee in the 10th Congressional District and a three-way fight for the GOP's U.S. Senate candidate to challenge incumbent Democratic Sen. Mark Warner in November.

Polls are open until 7 p.m. Anyone in line by then will be allowed to vote.

Virginia does not register voters by party, so any of the county's more than 817,000 registered voters can choose either the Democratic or Republican primary ballot, according to FFXnow. There is no Democratic primary contest in the 10th District, where Vienna sits, meaning the Republican races are the only competitive action on the ballot for most town residents.

U.S. House: 10th District

Three Republicans are competing for the nomination to face Democratic Rep. Suhas Subramanyam, who won the seat in 2024 and is unopposed in the primary. The 10th District covers parts of Fairfax County, along with Loudoun, Fauquier\ and Rappahannock counties, parts of Prince William County, and the cities of Manassas and Manassas Park.

The candidates, as profiled by the Virginia Mercury:

  • Dave Beckwith, a retired U.S. Air Force colonel and former deputy assistant secretary of defense, running on national security and government management. He leads the field in overall fundraising.
  • Julie Perry, a Fairfax County teacher who previously ran for the state Senate, emphasizing education, federal spending and opposition to diversity programs in public schools. She leads in small-dollar donations.
  • Anthony Suttles, whose background is in national security and economics.

The Virginia Public Access Project rates the 10th District as leaning Democratic, making the general election competitive for whichever Republican emerges.

U.S. Senate

Three Republicans are also vying for the right to challenge Warner, who is seeking a fourth six-year term. Virginia has not elected a Republican senator since John Warner won his final term in 2002. The incumbent has raised nearly $22 million and reported more than $14 million cash on hand, according to the Virginia Mercury's July 15 analysis.

The Senate primary candidates:

  • Bert Mizusawa, a retired Army major general and former Pentagon official, focusing on military readiness and national security.
  • Kim Farington, a Northern Virginia business owner and former public accountant for federal agencies, centering her campaign on inflation, government spending, and border security.
  • David Williams, a businessman, U.S. Navy veteran, and former federal employee running as a political outsider on cutting taxes and reducing the size of government.

David Richards, a political science professor at the University of Lynchburg, told the Virginia Mercury on July 15 that he does not see the Senate race as Warner's to lose, noting the Democrat won in 2020 by about 12 percentage points with Trump on the ballot.

Why the August date

This primary is running about two months later than Virginia's traditional June date. The delay stems from the 2026 congressional redistricting referendum and uncertainty over which district map would govern the races. The primary uses the 2021 district boundaries after the U.S. Supreme Court rejected Virginia's bid to restore a Democratic-drawn congressional map.

How to vote

Voters must present an accepted form of ID at the polls: a Virginia driver's license, U.S. passport, employee photo ID, student ID or voter confirmation documents. Those without ID may sign a confirmation statement; otherwise they cast a provisional ballot verified after the election.

Mail-in ballots must be postmarked by Tuesday, Aug. 4, and received by noon Friday, Aug. 7. A secure drop box is available at the Fairfax County Government Center, and ballot drop boxes are at all polling places until 7 p.m.

Same-day voter registration is available Tuesday, Aug. 4. New registrants cast a provisional ballot verified after election night.

Voters can confirm their polling place at the Virginia Department of Elections citizen portal (vote.elections.virginia.gov). The U.S. Department of Justice is sending election monitors to Fairfax County. Fairfax County Office of Elections spokesperson Sean Stewart said the DOJ's Civil Rights Division sought information on the county's bilingual election program for Spanish and Vietnamese speakers.

Unofficial results will be posted on the Virginia Department of Elections website (elections.virginia.gov) after polls close. The general election is Tuesday, Nov. 3.
