Mark Keough holds a commanding lead in the 2026 Montgomery County Judge race as the Republican incumbent seeking a third term. He secured the GOP nomination in the March primary by defeating challenger Wayne Mack 51% to 49% and now faces Democrat James Graf, who advanced unopposed. Montgomery County’s consistent Republican voting patterns in recent cycles, combined with Keough’s emphasis on property tax reductions, law enforcement funding, and infrastructure priorities, underpin trader consensus on his strong position heading into the November 3 general election. Graf’s campaign would require overcoming the county’s partisan baseline and typical turnout dynamics to close the gap. Late developments such as a major scandal, health event, or significant national political shift could still alter the outcome before ballots are cast.
