Therese Terlaje holds the strongest position in the August 1, 2026, Democratic primary for Guam governor, reflecting her extended service as a territorial senator and former legislative speaker alongside a recent filing with running mate Sabina Perez. Josh Tenorio, the current lieutenant governor who announced early and paired with Tina Rose Muña Barnes, draws support from incumbency advantages but trails in trader assessments. Joe S. San Agustin, another senator teaming with Dwayne San Nicolas, maintains a smaller share consistent with later entry into the three-way contest for the open seat. With the primary roughly two months away and no major recent endorsements or polling shifts reported, the current odds align with established name recognition and legislative records among the candidates.
