John Sidney McCain III (August 29, 1936 – August 25, 2018) was an American politician and naval officer who represented Arizona in the United States Congress for over 35 years, first as a U.S. representative from 1983 to 1987, then as a U.S. senator from 1987 until his death in 2018. A member of the Republican Party, he was the party's nominee in the 2008 presidential election. Born into the prominent McCain family in the Panama Canal Zone, McCain graduated from the U.S. Naval Academy in 1958 and received a commission in the U.S. Navy. He became a naval aviator and flew ground-attack aircraft from aircraft carriers. During the Vietnam War, he almost died in the 1967 USS Forrestal fire. While on a bombing mission during Operation Rolling Thunder over Hanoi in October 1967, McCain was shot down, seriously injured, and captured by the North Vietnamese. He was a prisoner of war until 1973. McCain experienced episodes of torture and refused an out-of-sequence early release. He sustained wounds that left him with lifelong physical disabilities. McCain retired from the Navy as a captain in 1981 and moved to Arizona. In 1982, McCain was elected to the House of Representatives, where he served two terms. Four years later, he was elected to the Senate, where he served six terms. While generally adhering to conservative principles, McCain also gained a reputation as a "maverick" for his willingness to break from his party on certain issues, including LGBT rights, gun regulations, and campaign finance reform where his stances were more moderate than those of the party's base. McCain was investigated and largely exonerated in a political influence scandal of the 1980s as one of the Keating Five. He then made regulating the financing of political campaigns one of his signature concerns, which eventually resulted in the passage of the McCain–Feingold Act in 2002. With Russ Feingold, McCain would receive the 1999 John F. Kennedy Profile in Courage Award. He was also known for his work in the 1990s to restore diplomatic relations with Vietnam. McCain chaired the Senate Commerce Committee from 1997 to 2001 and 2003 to 2005, where he opposed pork barrel spending and earmarks. He belonged to the bipartisan "Gang of 14", which played a key role in alleviating a crisis over judicial nominations. McCain entered the race for the 2000 Republican presidential nomination, but lost a heated primary season contest to George W. Bush. He secured the 2008 Republican presidential nomination, beating fellow candidates Mitt Romney and Mike Huckabee, though he lost the general election to Democratic presidential nominee Barack Obama. McCain subsequently adopted more orthodox conservative stances and attitudes and largely opposed actions of the Obama administration, especially with regard to foreign policy matters. In 2015, he became Chairman of the Senate Armed Services Committee. He refused to support Donald Trump in the 2016 presidential election and later became a vocal critic of the first Trump administration. While McCain opposed the Obama-era Affordable Care Act (ACA), he cast the deciding vote against the American Health Care Act of 2017, which would have partially repealed the ACA. After being diagnosed with glioblastoma in 2017, he reduced his role in the Senate to focus on treatment, dying from the disease in 2018.
