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 3 primary with 51% against Wayne Mack and now faces Democrat James Graf, who ran unopposed, in the November 3 general election. Montgomery County’s consistent Republican margins in recent cycles, combined with Keough’s record on budgeting, infrastructure priorities, and law enforcement funding, underpin trader consensus around his position. No major developments since the primary have altered the partisan baseline. A late-breaking scandal, health event, or unusually high Democratic turnout could theoretically narrow the gap, though the county’s electoral patterns make such shifts improbable before early voting begins October 19.
