PERRY, Ga. — Republican Nathan Deal accused Democrat Jason Carter of being inexperienced and unproven, while Carter zoned in on ethics complaints against the incumbent and Georgia's uneven economic recovery Tuesday, as the candidates sharpened their messages during their first head-to-head debate. The two and Libertarian Andrew Hunt sparred before a raucous crowd at the Georgia National State Fair. Deal, a 72-year-old former state senator and congressman elected to the governor's office in 2010, swung early and accused Carter of lacking leadership during his four-year-term in the state senate.
