In 1982, Kasich ran for Congress in Ohio's 12th congressional district, which included portions of Columbus as well as the cities of Westerville, Reynoldsburg, Worthington, and Dublin. He won the Republican primary with 83% of the vote and defeated incumbent Democrat U.S. Congressman Bob Shamansky in the general election by a margin of 50%-47%. He was re-elected eight times after 1982, winning at least 64% of the vote each time.  During his congressional career, Kasich was considered a fiscal conservative, taking aim at programs supported by Republicans and Democrats. He worked with Ralph Nader in seeking to reduce corporate tax loopholes.  Kasich was a member of the House Armed Services Committee for 18 years. He developed a "fairly hawkish" reputation on that committee, although he "also zealously challenged" defense spending he considered wasteful. Among the Pentagon projects that he targeted were the B-2 bomber program (teaming up with Democratic representative Ron Dellums to cut the program, their efforts were partly successful) and the A-12 bomber program (ultimately canceled by defense secretary Dick Cheney in 1991). He participated extensively in the passage of the Goldwater-Nichols Act of 1986, which reorganized the U.S. Department of Defense. He also pushed through the bill creating the 1988 Base Realignment and Closure Commission, which closed obsolete U.S. military bases, and successfully opposed a proposed $110 million expansion of the Pentagon building after the end of the Cold War. He also "proposed a national commission on arms control" and "urged tighter controls over substances that could be used for biological warfare."  Kasich said he was "100 percent for" the first Persian Gulf War as well as the 2001 invasion of Afghanistan, but said that he did not favor U.S. military participation in the Lebanese Civil War or in Bosnia. In 1997, with fellow Republican representative Floyd Spence, he introduced legislation (supported by some congressional Democrats) for the U.S. to pull out of a multilateral peacekeeping force in Bosnia. In the House, he supported the Comprehensive Anti-Apartheid Act, a Dellums-led initiative to impose economic sanctions against apartheid-era South Africa.
