Guerrero, the first person of native Chamorro descent to rise to the highest office in the territory, three Guamanian Governors have been affiliated with the party: Ricardo J. Bordallo, Carl T.C.

This dominance continued even when the Territorial Party was formed near the end of the decade and there was finally two-party competition in the electoral process.

[2] In 1963, President John F. Kennedy appointed the first Guamanian and Chamorro Governor of Guam, Manuel F. Leon Guerrero.

[7] In the first race for elected governor, Manuel F. Leon Guerrero teamed up with Dr. Antonio C. "Tony" Yamashita, President of the University of Guam.

They were challenged by Speaker Joaquin C. Arriola and retired Judge Vicente Bamba and team of Senator Ricardo J.

After the primary election, Bordallo-Taitano mounted a vigorous but unsuccessful campaign for Governor against Carlos Camacho and Kurt Moylan.

Governor Bordallo had the largest inauguration Guam had ever seen with about 15,000 people in the Plaza de Espana.

Bordallo chaired the Commission for Self-Determination and spearheaded the drafting of the Guam Commonwealth Act developed by June 4, 1986.

Gutierrez focused his work in the areas of infrastructure so that all the marginalized people will be brought into the 20th century before it went out and also pushing for economic development by aggressively completing 85% of his Vision 2001 plan by the end of 1999.

Despite a super majority Republican Legislature that opposed virtually every executive initiative, the Gutierrez-Bordallo administration was successful in guiding the island through the rough waters of economic downturns throughout the region.

[15] Buildings on the island made of reinforced concerted fared well, as opposed to light metal-frame structures, which more often were completely destroyed.

[14] A complete island-wide power outage followed the typhoon; damage to the main electrical transmission and distribution system was estimated at USD16 million.

Strong waves washed away a few coastal roads in the northern portion of the island, leaving them temporarily closed.

The waves surpassed the seawall at Apra Harbor, damaging the road and infrastructure of the seaport; many boats were washed ashore after breaking from their moorings.

[17] In the 1998 General Election, Gutierrez-Bordallo faced the Republican team of Former Governor Joseph Franklin Ada and Senator Felix Perez Camacho.

Gutierrez and Madeleine Z. Bordallo, President William Jefferson Clinton visited Guam on November 23, 1998.

Thousands of Guamanians gathered on the field in front of the Ricardo J. Bordallo Governor's Complex to see President Clinton.

His second term in office was marked by political instability caused by the 1998 election challenges, a supermajority Republican (12–3) Guam Legislature, an unsuccessful Recall Movement in 2000 after the Supreme court decision came out giving Gutierrez/Bordallo the win, the "rolling" power outages left behind by the Ada/Blas administration, the destruction of the island's infrastructure by Supertyphoons Chata'an, Paka, and Pongsona.

In February 2017, former senator Lourdes A. Leon Guerrero officially announced her bid to be the next Governor of Guam.

After years of frustration, then-Senator Ricardo J. Bordallo authored Public Law 7-173, which created an unofficial delegate to the U.S. Congress.

After Won Pat's ardent efforts in Washington to press for an elected Governor as well as an official delegate, the U.S. Congress passed the Guam Elective Governor Act in 1968 and later authorized the creation of Guam's delegate to the U.S. House of Representatives.

The 2014 General Election saw the vacancy left by the late Vicente "Ben" C. Pangelinan of an incumbent Democratic Senator, but their seats were taken by a newcomer Nerissa Bretania Underwood the wife of former Democratic Congressman and current University of Guam President Robert A. Underwood.

Five Mayors, Frankie A. Salas of Asan, Jessy Gogue of Chalan Pago-Ordot, Rudy A. Paco of Mongmong-Toto-Maite, Dale E. Alvarez of Santa Rita and Vicente S. Taitano of Talofofo were reelected for the first time in 2012.

Hoffman and Vice Mayor Rudy Don Iriarte have held their positions since they were first elected by the people of Sinajana in 2012.
