Therese Terlaje holds a commanding lead in the Democratic primary for Guam governor on August 1, driven by her established role as Senate speaker and broad name recognition among voters in an open contest without the incumbent. Her ticket with Sabina Perez benefits from recent candidate filings confirmed after the May 1 deadline and a track record of strong legislative performance that has translated into early polling edges. Lt. Gov. Josh Tenorio, paired with Tina Muña-Barnes, draws support from his executive branch experience but trails as the field remains fragmented. Sen. Joe San Agustin, running with Dwayne San Nicolas, occupies a distant third position with limited momentum amid the three-way Democratic matchup. Early campaign activity and potential endorsements in key precincts could still shape turnout before absentee voting begins.
