Political action committees in Georgia operate with little oversight. They don’t have to report spending that’s not campaign-related. Nothing in campaign law addresses how PACs spend their money, the State Ethics Commission observed in 2008. “We did some advisory opinions because we were hoping people would get outraged enough and push for legislation,” said Rick Thompson, the agency’s former executive secretary. It hasn’t worked so far. Georgia lawmakers are sifting through a slew of ethics bills, but none address PAC spending.
