The Republican Party of Guam (), commonly referred to as Guam GOP (abbreviation for Guam Grand Old Party), is a political party in Guam affiliated with the United States Republican Party.

In the 2024 general election, Republican Party candidates won 9 out of 15 seats in the Guam Legislature.

History The Republican Party of Guam stems from the old Territorial Party of Guam, which existed from 1956 through 1968.. The Territorial Party was established in 1956 by discontented former Popular Party members,. including Frank D. Perez,. Pedro Leon Guerrero, Edward T. Calvo, Cynthia Torres, B. J. Bordallo, Vicente Reyes, Felix Carbullido, and Antonio Duenas. The Territorial Party had only one successful election, in 1964, when it won a majority in the Guam Legislature with 13 thirteen of the 21 twenty-one seats.

This changed during the 1966 election, when the Territorials lost all twenty-one seats to the Democrats. The Territorials' demise came after they blocked a popular urban renewal plan, which was supported by the Democrats, as the Territorials backed private investment. The Territorial Party dissolved soon after.

On November 21, 1966, a few weeks after the general election of that year, former Governor Joseph Flores, along with former Territorial senators Carlos Garcia Camacho, Kurt S. Moylan, and Vicente C. Reyes, officially formed the Republican Party of Guam. Other Territorials soon became active, including Senators G. Ricardo Salas and Frank D. Perez. The new Republicans were careful not to portray their new party as a criticism of the Territorial Party, whose members they hoped to attract.

Republican governors of Guam At the young age of forty-four, Carlos Camacho succeeded Governor Manuel F.L. Guerrero as Governor of Guam, with Kurt Moylan appointed as lieutenant governor. Camacho's term as appointed governor lasted only eighteen months, due to the Elective Governor Act that was signed into law by the US Congress in 1968, allowing for Guam's citizens to choose their governor. The act took effect in 1970 when Guam's first election was held. Camacho's term was best remembered for his Christmas 1969 visit to the troops from Guam who were fighting in Vietnam.

Camacho–Moylan administration Camacho first selected senator G. Ricardo Salas as his running mate but later announced that Kurt Moylan would be the Republicans' candidate for lieutenant governor. The Democratic primary was a close race between former governor Manuel F. L. Guerrero, senator Ricardo Bordallo and attorney and former speaker Joaquin C. "Kin" Arriola. After a close primary and a contentious runoff election, Guerrero defeated Bordallo, and in the general election Camacho–Moylan defeated Bordallo–Taitano.

Camacho and Moylan's historic inauguration was held on January 4, 1971, at the Plaza de España in Agana. He uses the resources of the government to enhance economic opportunities by granting incentives through the Guam Economics Development and offering various forms of assistance to the private sector. During his entire five and a half years in office, Camacho presided over one of the largest eras of hotel construction activities on Guam, with construction finishing or starting on the Kakue Hotel, Reef Hotel, Hilton Hotel, Okura Hotel, Fujita Tumon Beach, Continental Travelodge, and Guam Dai Ichi Hotel.

Camacho also initiated massive road projects that were continued by his successors, including the widening of Marine Drive (now Marine Corps Drive) from Hospital Road north to Route 16 in Harmon, and the reconstruction of other major highways in the villages of Agat, Dededo, and Tamuning, among others.

He is also credited with enticing many educated Chamorros back to Guam, to reverse what was seen as a "brain drain" at the time, including Tony Palomo, Greg Sanchez, Mary Sanchez, Tony Unpingco, Dr. Pedro Sanchez, Dr. Katherine Aguon, Juan C. Tenorio, Bert Unpingco, Ben Perez, Eddie Duenas, Joseph F. Ada and Frank Blas. Many of them took jobs with the government of Guam as administrators and later became senators. Camacho also kept on other able administrators even if they were not of his party affiliation which served to stabilize the government.

As a team, Camacho and Moylan worked to develop economic opportunities by creating incentives to attract business and encourage local participation in business. At the time Guam elected its first governor the federal government still had control over much of the island's utilities and roads. They struggled to work toward gaining more self-government and self-determination.

In the 1974 gubernatorial election, Camacho withstood a primary challenge by Paul McDonald Calvo, but was defeated for reelection in a re-match with Senator Ricardo Bordallo, who won the election.. An election challenge by the Bordallo–Sablan campaign went all the way to the U.S. Supreme Court. Following his unsuccessful bid for reelection as governor, Camacho resumed his career as a dentist.

Calvo-Ada administration Calvo ran for governor again in 1978, this time with popular senator Joseph F. Ada. Calvo's image of a successful business executive resonated well with the voters as he ran on a "balance-the-budget" campaign and attacked the Bordallo administration for the huge jump in the budget deficit and high crime rate. Calvo built a strong political organization, complete with regional and village groups, and had the financial backing not only of Calvo's Enterprises but of supporters in the business community. Bordallo, meanwhile, was hurt as his running mate, Sablan, ran against him in the primary, and Calvo-Ada won the election with 52 percent of the votes.

During his first year as governor, Calvo reduced the government of Guam's deficit by $27 million, but the deficit continued to climb for the rest of his term due mainly to long-standing problems with tax collections.

Guam's economy began to regain health under Calvo's administration, as he sought to attract new businesses to Guam, including a tuna-fishing fleet, a garment manufacturer, and hotel construction. Visitor arrivals also registered sharp increases.

But Calvo's term as governor was marred by the teacher's strike of 1981, which lasted many months and caused deep divisions in Guam's education system. He lost to Bordallo in the 1982 election.

Ada-Blas administration

First term His running mate and lieutenant governor was former senator Frank Blas. Ada served numerous terms in the Guam Legislature, becoming the first Republican speaker of the Legislature when the Republicans captured control of the body from the Democratic Party. Ada was elected Lt. Governor of Guam with running mate Paul McDonald Calvo in 1978, but declined the opportunity to serve as Calvo's running mate for re-election in 1982 and instead returned to the Legislature. Calvo lost the subsequent election to Ricky Bordallo. Ada is the only Guam political leader to serve as Speaker, lieutenant governor and governor. He stewarded Guam's economic expansion and pushed, successfully, for the return of land held by the US military.

When Ada began his first term Guam was in the throes of an economic recession with the government suffering under a crushing deficit. Ada put all his administration's efforts toward Guam's economic recovery, and eventually, he presided over one of the fastest-growing and strongest economies in the island's history due in part to a growth in tourism from a booming Japanese economy. He launched an austerity program at the start of his term and followed it with a program to encourage investment and trade from Asia. He eliminated the government deficit in three years. Despite a decrease in federal spending, Guam's economy doubled and some 25,000 new jobs were created. A majority of these jobs were in Guam's growing private sector. During Ada's first term, private sector employment outstripped public sector employment in Guam's economy for the first time in the modern era.

As chairperson of the Commission on Self-Determination, established in 1980 to lead the way toward determining a new political status for Guam, Ada presided over the completion of the Guam Commonwealth Act and presented to the people of Guam for approval in a plebiscite. Upon the Act's approval, Ada took it to US Congress. A strong advocate for self-government and self-determination for Guam, he called for an end to Guam's colonial status and pushed for the liberation of Guam's economy from federal regulations. Congress, however, did not act on the Guam Commonwealth Act and Guam's political status remains unresolved.

Ada believed that Guam needed to be financially healthy and not dependent on the US government in order to move forward politically. He said the federal government has tied Guam's hands more than once pointing to postwar security clearance, federal land takings for US bases, and the Jones Act which puts Guam at a financial disadvantage for shipping.

To address those concerns Ada said he supported the newly developed qualifying certificate program at the Guam Economic Development Authority to bring in foreign investment, pushed for good fuel rates and port lease fees to bring tuna transshipment to Guam, and worked on getting a visa waiver for visitors to Guam from Korea and Taiwan, all of which helped move Guam away from being dependent on US federal dollars. He also directed floating the first bond for infrastructure rather than ask for more federal funds.

Second term In his second term, Ada capitalized on the fruits of his economic recovery program and made the largest investment in education in Guam up to that time. He directed the floating of a bond which made some $170 million available for the construction of a new high school in southern Guam (now Guam Southern High School), new elementary schools in Tamuning, Inarajan and Dededo, and reconstruction of schools in Upi and Ordot-Chalan Pago. Additionally, many new classrooms were built to relieve overcrowding in schools around the island. Operating budgets for the public schools were increased annually. Under Ada computers and computer classes were introduced in all Guam schools. At the end of his term, every grade level in every school had access to computer classes.

Guam suffered from a string of natural disasters during the second Ada administration. Four typhoons, one after another, hit Guam in 1991, with Typhoon Omar causing the most damage. On 8 August 1993 Guam was rocked by a very large earthquake. Measuring 7.8 on the moment magnitude scale, the shock had a maximum Mercalli intensity of VIII (Severe). Damage ran into millions of dollars, though only two buildings were destroyed. These disasters, combined with a recession in Japan, caused the tourism industry to suffer for a time.

Camacho-Moylan administration Camacho-Moylan went on to defeat Speaker Antonio "Tony" Unpingco with his running mate Eddie Baza Calvo as a future governor in the Republican primary election on August 31, 2002, and ran against Guam Delegate Robert A. Underwood and his running mate, Senator Thomas "Tom" C. Ada for the general election. In 2002, Camacho teamed up with fellow senator Kaleo Moylan to run for Guam's governor and lieutenant governor and defeated Democratic contenders Guam Delegate Robert Underwood and Senator Thomas "Tom" Ada.

Guam was slammed by Super Typhoon Pongsona on 8 December 2003, shortly after Camacho and Moylan were elected into office. They opted not to have a formal inaugural celebration, due to the state of the island and instead chose to be sworn in with a ceremony at the Plaza de España at midnight after a celebratory mass at the Dulce Nombre de Maria Cathedral Basilica in Hagåtña – all under candle light.
