What Cain has done on taxes and economic policy is similar to what John Edwards did on health care in 2008. He came out of the box first with a comprehensive plan, and it drew his competition entirely to his left. Even though Cain is being savaged for his wealth redistribution scheme, he’s drawing everyone to his right. Rick Perry’s introducing a flat tax. Mitt Romney endorsed a version of the Paul Ryan plan for Medicare vouchers. It’s become follow-the-leader in the Republican Party, and Cain is the leader. Regressive taxes and wealth distribution upward is the order of the day.
