- He joins a Democratic field that includes Sara Rodriguez, Mandela Barnes, David Crowley, Kelda Roys, Francesca Hong and Missy Hughes.
- Republican candidates include U.S. Rep. Tom Tiffany and Washington County Executive Josh Schoemann.
- The primary is scheduled for August 2026 before the November general election, and some Democrats question Brennan’s path given his limited statewide name recognition.
