Cox's abrupt departure as head of the Kentucky Revenue Department was announced by the Beshear administration the day AFTER Cox had resigned. Several sources say Cox left because of a medical "episode" and perhaps because he wasn't enjoying Frankfort politics as much as he expected. Boswell tells me Cox didn't explain why he was quitting his state government job after little more than six months. But the Owensboro democrat says Cox has agreed to raise money and help coordinate his campaign against republican Brett Guthrie. Boswell says he's asked Cox to manage his campaign and expects to get an answer when Cox returns from a trip to Florida.
