The United States was drawn into World War II when the Empire of Japan attacked Pearl Harbor on December 7, 1941. Six months later, Bush enlisted into the US. Navy immediately after he graduated from Phillips Academy on his eighteenth birthday. He became a naval aviator training for aircraft carrier landings and takeoffs on the USS Sable. After completing the 10-month course, he was commissioned as an ensign in the United States Naval Reserve at Naval Air Station Corpus Christi on June 9, 1943 (just three days before his 19th birthday), which made him the youngest naval aviator to that date.  In September 1943, he was assigned to Torpedo Squadron (VT-51) as the photographic officer. The following year, his squadron was based on USS San Jacinto as a member of Air Group 51, where his lanky physique earned him the nickname "Skin". During this time, the task force was victorious in one of the largest air battles of World War II: the Battle of the Philippine Sea.  After Bush's promotion to Lieutenant (junior grade) on August 1, 1944, San Jacinto commenced operations against the Japanese in the Bonin Islands. Bush piloted one of four Grumman TBM Avenger aircraft from VT-51 that attacked the Japanese installations on Chichijima. His crew for the mission, which occurred on September 2, 1944, included Radioman Second Class John Delaney and Lieutenant Junior Grade William White. During their attack, the Avengers encountered intense anti-aircraft fire; Bush's aircraft was hit by flak and his engine caught on fire. Despite the fire in his aircraft, Bush completed his attack and released bombs over his target, scoring several damaging hits. With his engine ablaze, Bush flew several miles from the island, where he and one other crew member on the TBM Avenger bailed out of the aircraft; the other man's parachute did not open. Bush waited for four hours in an inflated raft, while several fighters circled protectively overhead until he was rescued by the lifeguard submarine USS Finback. For the next month, he remained on Finback and participated in the rescue of other pilots. Several of those shot down during the attack were executed, and their livers were eaten by their captors.  In November 1944, Bush returned to San Jacinto and participated in operations in the Philippines until his squadron was replaced and sent home to the United States. Through 1944, he flew 58 combat missions for which he received the Distinguished Flying Cross, three Air Medals, and the Presidential Unit Citation awarded to San Jacinto.  Because of his valuable combat experience, Bush was reassigned to Norfolk Navy Base and put in a training wing for new torpedo pilots. He was later assigned as a naval aviator in a new torpedo squadron, VT-153, based at Naval Air Station Grosse Ile, Michigan. The unconditional surrender of Japan was announced on August 15, 1945. Bush was honorably discharged the following month.  Bush served as Chairman of the Republican Party for Harris County, Texas in 1964, but wanted to be more involved in policy making, so he set his sights high: he aimed for a U.S. Senate seat from Texas. After winning the Republican primary, Bush faced his opponent, incumbent Democrat Ralph W. Yarborough, who attacked Bush as a right-wing extremist. Bush was a strong supporter of Republican Senator Barry Goldwater, who headed the Republican ticket as the presidential candidate. Like Goldwater, Bush strongly opposed civil rights legislation in the name of states rights. Yarborough, a leading Texas liberal, supported the civil rights legislation and was reelected by 56% - 44%. The Republican candidate for governor, Jack Crichton of Dallas, who often campaigned alongside Bush before the election, lost by a much wider margin to Governor John B. Connally Jr. Bush and the Harris County Republicans played a role in the development of the new Republican Party of the late 20th century. First, Bush worked to absorb the John Birch Society members, who were trying to take over the Republican Party. Second, during and after the civil rights movement, Democrats in the South who were committed to segregation left their party, and although the "country club Republicans" had differing ideological beliefs, they found common ground in hoping to expel the Democrats from power.  Bush was elected in 1966 to a House of Representatives seat from the 7th District of Texas, defeating with 57 percent of the ballots cast the Democrat Frank Briscoe, the district attorney of Harris County known for his law-and-order credentials and a cousin of later Governor Dolph Briscoe. Bush was the first Republican to represent Houston in the U.S. House. Bush's representative district included Tanglewood, the Houston neighborhood that was his residence; his family had moved into Tanglewood in the 1960s. His voting record in the House was generally conservative: Bush voted for the Civil Rights Act of 1968, although it was generally unpopular in his district. He supported the Nixon administration's Vietnam policies, but broke with Republicans on the issue of birth control, which he supported. Despite being a first-term congressman, Bush was appointed to the powerful House Ways and Means Committee, where he voted to abolish the military draft. He was elected to a second term in 1968.  In 1970 Nixon convinced Bush to relinquish his House seat to run for the Senate against Ralph Yarborough, a fierce Nixon critic. In the Republican primary, Bush easily defeated conservative Robert J. Morris, by a margin of 87.6% to 12.4%. Nixon came to Texas to campaign in Longview for Bush and gubernatorial candidate Paul Eggers, a Dallas lawyer who was a close friend of U.S. Senator John G. Tower. Former Congressman Lloyd Bentsen, a more moderate Democrat and native of Mission in south Texas, defeated Yarborough in the Democratic primary. Yarborough endorsed Bentsen, who defeated Bush, 53.4 to 46.6%. As Bush's political career waned, he moved out of Houston and sold his first Tanglewood house, but for periods of time continued to reside in Tanglewood.  Bush had decided in the late 1970s that he was going to run for president in 1980; in 1979, he attended 850 political events and traveled more than 250,000 miles (400,000 km) to campaign for the nation's highest office. In the contest for the Republican Party nomination, Bush stressed his wide range of government experience, while competing against rivals Senator Howard Baker of Tennessee, Senator Bob Dole of Kansas, Congressman John Anderson of Illinois (who would later run as an independent), Congressman Phil Crane, also of Illinois, former Governor John Connally of Texas, former Minnesota Governor Harold Stassen, and the front-runner Ronald Reagan, former actor, and Governor of California.  In the primary election, Bush focused almost entirely on the Iowa caucuses, while Reagan ran a more traditional campaign. Bush represented the centrist wing in the GOP, whereas Reagan represented conservatives. Bush famously labeled Reagan's supply side-influenced plans for massive tax cuts "voodoo economics". His strategy proved useful, to some degree, as he won in Iowa with 31.5% to Reagan's 29.4%. After the win, Bush stated that his campaign was full of momentum, or "Big Mo". As a result of the loss, Reagan replaced his campaign manager, reorganized his staff, and concentrated on the New Hampshire primary. The two men agreed to a debate in the state, organized by the Nashua Telegraph, but paid for by the Reagan campaign. Reagan invited the other four candidates as well, but Bush refused to debate them, and eventually they left. The debate proved to be a pivotal moment in the campaign; when the moderator, John Breen, ordered Reagan's microphone turned off, his angry response, "I am paying for this microphone," struck a chord with the public. Bush ended up losing New Hampshire's primary with 23% to Reagan's 50%. Bush lost most of the remaining primaries as well, and formally dropped out of the race in May of that year.  With his political future in doubt, Bush sold his house in Houston and bought his grandfather's estate in Kennebunkport, Maine, known as "Walker's Point". At the Republican Convention, Reagan selected Bush as his vice presidential nominee, placing him on the winning Republican presidential ticket of 1980.
