From a 1998 profile:

In the late '70s, he and his dad struck it rich when they discovered one of the nation's 50 largest natural gas reserves underneath a tract they owned in Utah. The uncertain nature of the wildcatter's life made the younger Anschutz "extremely pragmatic" and "a student of timing and cycles." In 1982, he became Colorado's first billionaire when he bailed out of the oil business just before global prices collapsed.
... Anschutz has always used his money for political influence. In 1993, he gave $100,000 to a think tank controlled by his old friend Bob Dole. In '95 and '96, he spent $360,000 backing Republicans, especially the successful 1996 Colorado senatorial run of veterinarian Wayne Allard, a National Rifle Association stalwart who proposed "hangings in the streets" as a criminal deterrent. In the crucial final days of the successful campaign to pass Colorado's Amendment 2, which restricted the right of the state's cities to pass civil rights protection for gays, Anschutz donated $10,000 to the amendment's backers, Colorado for Family Values. At heart, suggests the Denver Business Journal's Dubroff, Anschutz isn't that interested in politics: "He's more of a person who doesn't like government interference."
