What is all of a sudden a tight race for governor is about to have its Orvis moment. Massachusetts Sen. Scott Brown will campaign for GOP gubernatorial contender Tom Foley at an Oct. 9 rally in Glastonbury, Hearst Connecticut Newspapers has learned. Brown defied the odds with his upset of Democratic Attorney General Martha Coakley in January’s special election to fill the seat of the late Senate lion Ted Kennedy. Foley is now trying to tap some of the populist success of Brown, who made a fashion statement on the campaign trail with his trademark barn jacket. If imitation is the sincerest form of flattery, Foley should be in Brown’s good graces, having donned a barn jacket and jeans in one of his first television commercials called “Let’s Get to Work.”
