Ron Nirenberg secured the Democratic nomination for Bexar County Judge by defeating incumbent Peter Sakai in the March 2026 primary with 62 percent of the vote. As the former San Antonio mayor with strong name recognition and a substantial fundraising lead, Nirenberg enters the November general election against Republican Patrick Von Dohlen in a county where Democrats have won every countywide contest for more than a decade. Primary results and campaign finance reports reflect broad support for Nirenberg across Bexar County precincts. Trader consensus at 93.5 percent for Nirenberg aligns with these structural advantages in voter registration, historical turnout patterns, and the absence of competitive Republican countywide victories in recent cycles. Late developments such as a major scandal or unusually high Republican mobilization could narrow the margin, though both remain low-probability events before November 3.
