On Tuesday, Texas Gov. Rick Perry unveiled his 20-20 tax plan, which would scrap the existing tax code and install a flat 20 percent income tax rate. It also calls for a reduction in the corporate tax rate from 35 percent to 20 percent. Perry’s plan has won rave reviews from two-time presidential candidate and Forbes magazine publisher Steve Forbes. Why does he prefer the Perry plan to all the others coming from the GOP hopefuls? Why is he nervous about Herman Cain’s call for a national sales tax? What does he think of Mitt Romney’s 59-point plan? And what other reasons does he have for backing Gov. Perry. We discuss all these questions with Steve Forbes.
