Bob McEwen (born January 12, 1950) is an American politician of the Republican Party, and a former member of the United States House of Representatives from southern Ohio's Sixth District, from January 3, 1981 to January 3, 1993. Tom Deimer of Cleveland's Plain Dealer described him as a "textbook Republican" who is "opposed to abortion, gun control, high taxes, and costly government programs." In the House, he criticized government incompetence and charged corruption by the Democratic majority that ran the House in the 1980s. McEwen, who had easily won three terms in the Ohio House, was elected to Congress at the age of thirty to replace a retiring representative in 1980 and easily won re-election five times.
After a bruising primary battle with another incumbent whose district was combined with his, in which McEwen faced charges of bouncing checks on the House bank, he narrowly lost the 1992 general election to Democrat Ted Strickland. Following an unsuccessful run in the adjacent Second District in 1993, McEwen was largely absent from the Ohio political scene for a decade, until in 2005 he unsuccessfully sought the Republican nomination for Congress in the Second District special election to replace Rob Portman, who beat him in 1993, and finished second to the ultimate winner in the general election, Jean Schmidt. McEwen's 2005 platform was familiar from his past campaigns, advocating a pro-life stance, defending Second Amendment rights, and promising to limit taxes and government spending. In 2006, he unsuccessfully sought the Republican nomination in the Second District.
