IN: Maurice Robert "Mike" Gravel (; born May 13, 1930) is an American politician who was a Democratic United States Senator from Alaska from 1969 to 1981 and a candidate in the 2008 U.S. presidential election. Born and raised in Springfield, Massachusetts, by French-Canadian immigrant parents, Gravel served in the U.S. Army in West Germany, and he later graduated from the Columbia University School of General Studies. He moved to Alaska in the late 1950s, becoming a real estate developer and entering politics. He served in the Alaska House of Representatives from 1963 to 1966 and also became Speaker of the Alaska House.

In the late 1960s and early 1970s the U.S. Department of Defense was in the process of performing tests for the nuclear warhead for the Spartan anti-ballistic missile. Two tests, the "Milrow" and "Cannikin" tests, were planned, involving the detonation of nuclear bombs under Amchitka Island in Alaska. The Milrow test would be a one megaton calibration exercise for the second, and larger five megaton, Cannikin test, which would measure the effectiveness of the warhead. Gravel opposed the tests in Congress. Before the Milrow test took place in October 1969, he wrote that there were significant risks of earthquakes and other adverse consequences, and called for an independent national commission on nuclear and seismic safety to be created; he then made a personal appeal to President Nixon to stop the test. After Milrow was conducted, there was continued pressure on the part of environmental groups against going forward with the larger Cannikin test, while the Federation of American Scientists claimed that the warhead being tested was already obsolete. In May 1971, Gravel sent a letter to U.S. Atomic Energy Commission hearings held in Anchorage, in which he said the risk of the test was not worth taking. Eventually a group not involving Gravel took the case to the U.S. Supreme Court, which declined to issue an injunction against it, and the Cannikin test took place as scheduled in November 1971. Gravel had failed to stop the tests (notwithstanding his later claims during his 2008 presidential campaign). Nuclear power was considered an environmentally clean alternative for the commercial generation of electricity and was part of a popular national policy for the peaceful use of atomic energy in the 1950s and 1960s. Gravel publicly opposed this policy; besides the dangers of nuclear testing, he was a vocal critic of the Atomic Energy Commission, which oversaw American nuclear efforts, and of the powerful United States Congress Joint Committee on Atomic Energy, which had a stranglehold on nuclear policy and which Gravel tried to circumvent. In 1971, Gravel sponsored a bill to impose a moratorium on nuclear power plant construction and to make power utilities liable for any nuclear accidents; in 1975, he was still proposing similar moratoriums. By 1974, Gravel was allied with Ralph Nader's organization in opposing nuclear power. Six months before U.S. Secretary of State Henry Kissinger's secret mission to the People's Republic of China (P.R.C.) in July 1971, Gravel introduced legislation to recognize and normalize relations with China, including a proposal for unity talks between the P.R.C. and the Republic of China (Taiwan) regarding the Chinese seat on the U.N. Security Council. Gravel reiterated his position in favor of recognition, with four other senators in agreement, during Senate hearings in June 1971.

input: Mellencamp participated in the Vote for Change tour in October 2004 leading up to the 2004 U.S. Presidential election. That same month he released the two-disc career hits retrospective Words & Music: John Mellencamp's Greatest Hits, which contained 35 of his radio singles (including all 22 of his Top 40 hits) along with two new tunes, "Walk Tall" and "Thank You" - both produced by Babyface but written by Mellencamp. In 2005, Mellencamp toured with Donovan and John Fogerty. The first leg of what was called the Words and Music Tour in the spring of 2005 featured Donovan playing in the middle of Mellencamp's set. Mellencamp would play a handful of songs before introducing Donovan and then duetting with him on the 1966 hit "Sunshine Superman". Mellencamp would leave the stage as Donovan played seven or eight of his songs (backed by Mellencamp's band) and then return to finish off his own set after Donovan departed. On the second leg of the tour in the summer of 2005, Fogerty co-headlined with Mellencamp at outdoor amphitheaters across the United States. Fogerty would join Mellencamp for duets on Fogerty's Creedence Clearwater Revival hit "Green River" and Mellencamp's "Rain on the Scarecrow." Mellencamp released Freedom's Road, his first album of original material in over five years, on January 23, 2007. He intended for Freedom's Road to have a 1960s rock sound while still remaining contemporary, and he feels that goal was achieved. "We wanted to make sure that it had the same feeling of some of the great songs from the '60s but also had the message of today and had the backbeat of today. I think we came up with a pretty timeless sounding album", Mellencamp told his online radio station in late 2006. "Our Country", the first single from Freedom's Road, was played as the opening song on Mellencamp's 2006 spring tour, and the band that opened for him on that tour, Little Big Town, was called on to record harmonies on the studio version of "Our Country", as well as seven other songs on Freedom's Road. Although Mellencamp had always been outspoken and adamant about not selling any of his songs to corporations to use in commercials, he changed his stance and let Chevrolet use "Our Country" in Chevy Silverado TV commercials that began airing in late September 2006. "I agonized", Mellencamp told USA Today's Edna Gundersen in 2007 over his decision to license "Our Country" to Chevrolet. "I still don't think we should have to do it, but record companies can't spend money to promote records anymore, unless you're U2 or Madonna. I'm taking heat because no one's ever done this before. People have licensed songs that have already been hits, but nobody's licensed a brand-new song to a major company, and people don't know how to react." Mellencamp sang "Our Country" to open Game 2 of the 2006 World Series, and the song was nominated for a 2008 Grammy Award in the Best Solo Rock Vocal Performance category, but lost to Bruce Springsteen's "Radio Nowhere." Freedom's Road peaked at No. 5 on the Billboard 200 album chart by selling 56,000 copies in its first week on the market.
