Mark Keough secured the Republican nomination for a third term as Montgomery County Judge in the March 2026 primary, defeating challenger Wayne Mack by a narrow 51-49% margin. He now faces Democrat James Graf, who ran unopposed in his primary, in the November 3 general election. Montgomery County’s strong Republican voter base and Keough’s incumbency advantages, including prior tax rate reductions and law enforcement funding, underpin trader consensus around his commanding position. As of mid-September 2026, no major developments have altered this outlook. Late shifts could occur only from unforeseen events such as a significant scandal, health issue affecting the candidate, or unusually high Democratic turnout, though historical patterns in the county suggest limited scope for such changes.
