Herman Cain has surged to the front of the Republican presidential field and is making his 9-9-9 tax reform plan the centerpiece of his campaign. So what would be the impact of this plan?

What happens if Cain cannot move to a fair tax system and the nation gets stuck in what is supposed to be a transitional tax code? We discuss that and much more with Peter Sepp, executive vice president of the National Taxpayers Union.
