Vicente Ada leads trader consensus in the Guam Republican primary for governor, scheduled for August 1, 2026, reflecting his position as Vice Speaker and multiple terms in the legislature alongside running mate Edward John Calvo. Frank F. Blas Jr., the current Speaker of the Guam Legislature, trails with his ticket featuring former Guam Community College president Mary A.Y. Okada after their recent campaign launch. Marcel Camacho, Charlie Hermosa, and Douglas Moylan register lower probabilities amid a field of established legislative figures and newer entrants. Early platform announcements, such as the Ada-Calvo team's "Guam First Agenda" rollout, and candidate filings have shaped positioning, with no major polling or shifts reported in recent weeks. The race remains open ahead of the primary, consistent with historical patterns in territorial Republican contests.
