Bert Mizusawa
Republican · Challenger · U.S. Senate (VA) · 2026

Before politics: Served as Deputy Undersecretary of the Army, senior Pentagon official, CIA adviser, and president of a consulting firm.
Their shot at this seat
Bert Mizusawa faces an uphill battle given the incumbent's massive fundraising advantage and the state's deep partisan lean, meaning a victory is highly improbable unless a major shift in the national environment occurs.
Who's behind them
Bert Mizusawa is currently visible but lacks the institutional and financial backing necessary to mount a truly competitive, high-tier statewide campaign.
What could go wrong
Bert Mizusawa must overcome his history of ballot access difficulties to maintain credibility, while Mark Warner remains largely insulated from his single unproven allegation.
Why they fit this seat
The candidate’s military background provides a specific, professional platform that could resonate with voters looking for a change in Virginia’s long-held Senate representation.
Key contrasts
supports tax simplification and debt reduction
advocates incremental economic shifts over radical transformation
Who this moves: Seniors and voters concerned with inflation and tax policy.
