The Guam governor election delivered the first decisive result of the 2026 United States midterm elections on Tuesday, November 3, 2026, as Republicans Tony Ada and his running mate E.J. Calvo won the governorship of the Pacific island territory and ended eight years of Democratic control. Unofficial figures from the Guam Election Commission put Ada and Calvo at 15,945 votes, or 51.45 percent, against 14,925 votes, or 48.15 percent, for Democrats Therese Terlaje and Sabina Perez, a margin of about 1,020 votes. Terlaje conceded, and the result marked the first time since 2014 that a Republican has been elected governor of Guam.

Key Points

• Republicans Tony Ada and E.J. Calvo won Guam's governorship with 51.45 percent of the unofficial vote, beating Democrats Therese Terlaje and Sabina Perez.
• The margin was about 1,020 votes, and Terlaje conceded. Results remain unofficial until the Guam Election Commission completes its canvass and certifies them.
• Outgoing Democratic Governor Lou Leon Guerrero was term-limited and could not seek a third consecutive term, ending eight years of Democratic control.
• Republicans also won the Guam Legislature, eight seats to seven, while Democrat Alicia Limtiaco defeated Republican delegate James Moylan for Guam's seat in Congress.
• President Donald Trump hailed the result on Truth Social as a Republican breakthrough in a place long considered strongly Democratic.

What Happened

Guam voters went to the polls on Tuesday, November 3, 2026, as part of the nationwide midterm elections, choosing a governor and lieutenant governor, all 15 members of the Guam Legislature, a delegate to Congress and an attorney general, among other offices. The governor's race quickly produced a clear, if narrow, winner. Ada and Calvo led Terlaje and Perez by just over three percentage points in the unofficial count, a gap of roughly 1,020 votes out of about 30,870 cast for the two tickets.

The legislative result reinforced the Republican night in Hagåtña, the island's capital. Republicans took eight of the 15 seats in the Guam Legislature, against seven for Democrats, giving the incoming Republican administration a working majority in the territory's lawmaking body. That majority matters because Guam's governor and legislature share power over the budget, public services and the laws that govern daily life on the island, and a divided government has often slowed both.

Background/Context

Guam is a United States territory in the western Pacific, and its residents are American citizens who cannot vote for president and are represented in Congress by a non-voting delegate. That status gives the governor an unusually large role: the governor is the island's chief executive, its most prominent voice in Washington and, in practice, its head of government for most domestic matters.

Leon Guerrero, a Democrat, had led the territory for eight years but was barred by term limits from seeking a third consecutive term. Her departure therefore guaranteed a new governor regardless of party, and the 2026 race became a contest over who would define the next chapter for the island.

Guam Governor Election: What the Numbers Show

The unofficial numbers tell a story of a closely divided electorate. Ada and Calvo's 51.45 percent share was a clear victory but not a landslide, and the roughly 1,020-vote margin means that a small shift in turnout in any of Guam's villages could have changed the outcome. Terlaje and Perez's 48.15 percent share shows that Democratic support on the island remains deep, even in a race the party lost.

The split-ticket pattern elsewhere on the ballot underlines that closeness. While Republicans won the governor's office and the legislature, Democrat Alicia Limtiaco defeated incumbent Republican delegate James Moylan for Guam's non-voting seat in Congress, giving Democrats a voice in Washington even as they lost power at home. In the attorney general's race, Phillip Tydingco beat incumbent Doug Moylan, adding another change at the top of the island's government.

Reactions/Quotes

President Donald Trump was quick to claim the result as a national signal. Writing on Truth Social, he congratulated Ada and wrote that Guam, "which has always been considered strongly Democrat, just had an early call for a REPUBLICAN Victory" and that Republicans had won the legislature majority, calling it hopefully "an indication for things to come".

Why It Matters

The Guam result matters first for Guam itself. A new governor and a legislature controlled by the same party will have unusual freedom to set the island's budget, pursue their priorities and reshape the territorial government, at least in the early months of the administration. How Ada and Calvo use that opening, and whether they can hold together a narrow legislative majority, will shape services, spending and development on the island for years.

Finally, the result carries a modest national signal. Early results are often over-read on election night, and Guam's small electorate cannot predict the outcome of large mainland states. But as the first decisive result of the night, it gave Republicans an early talking point and set a tone for the hours of counting that followed, in a cycle already defined by record campaign spending and intense competition for control of Congress.

What Happens Next

The immediate next step is certification. The Guam Election Commission will complete its canvass of the vote, check the count and formally certify the results, at which point Ada and Calvo's victory becomes official and the transition to a new administration can proceed in full. The legislature's new eight-to-seven Republican majority will also be seated, and the island's government will begin the work of handing over offices, budgets and pending decisions.

Attention will then turn to the new administration's first moves: its budget proposals, its approach to the legislature and its dealings with Washington, including the federal agencies and members of Congress whose decisions affect Guam's military installations and its economy. Limtiaco, as the island's new delegate in Congress, will be a key counterpart in that work, even though she belongs to the opposing party, and the relationship between the governor's office and the delegate's office will be closely watched.
