State Sen. Tom McClintock beat former Rep. Doug Ose by 15 points on Tuesday to capture the Republican nomination in California’s 4th district, setting up a general-election matchup with the 2006 Democratic nominee, retired Air Force officer and former police administrator Charlie Brown. All precincts were reporting as of Wednesday morning, according to the unofficial results posted by the California secretary of state’s Web site. Rep. John Doolittle (R) is retiring. McClintock defeated Ose 53.7 percent to 38.7 percent, despite being significantly outspent thanks in part to Ose’s massive personal war chest, from which he drew heavily over the past few months. Brown won his primary over nominal opposition with 88 percent of the vote. Brown came close to knocking off Doolittle in 2006, but that was likely the result of the incumbent’s problems with multiple ethics-related issues. The northern California 4th district is solid conservative territory, and should be friendly to McClintock once all the votes are counted on Nov. 4. Meanwhile, in California’s Republican-leaning 52nd district, Marine Reservist Duncan D. Hunter won a four-way GOP primary with 72.6 percent of the vote and looks to cruise to victory in November in the seat his father, Rep. Duncan Hunter (R), has held for almost 28 years. Congressman Hunter is retiring after an unsuccessful presidential bid. Hunter will face military veteran Mike Lumpkin in the general election. Lumpkin beat teacher Vickie Butcher in the Democratic primary 58.6 percent to 41.4 percent. — David M. Drucker
