OKMULGEE, Okla. – The television ads look and sound like any others that inundate voters’ living rooms in the final weeks before an election. Ominous music. Faded, unflattering official profile pictures. An authoritative voice attacking the ad’s subjects, saying they added “millions to the costs of doing business” in the state and are “activist” liberals. Then there’s the opposing ad praising the same people, saying they “protected our public schools” and “stood up for our children.”
