Therese Terlaje holds the lead in trader consensus for the 2026 Guam gubernatorial race due to the territory’s historical Democratic advantage and the open seat created by term-limited incumbent Lou Leon Guerrero. Both major-party nominees emerged from competitive August 1 primaries, with Terlaje defeating Josh Tenorio by a narrow margin in the Democratic contest and Vicente Ada securing a stronger victory over Frank Blas Jr. on the Republican side. The November 3 general election features Terlaje paired with Sabina Perez against Ada and Edward Calvo, with early voting set to begin October 8. Limited differentiation has emerged at candidate forums on shared issues such as economic development and healthcare, and no major late-breaking developments have altered positioning in recent weeks.
