One of the consummate arguments in politics is over tax policy, and the 2012 presidential election is no exception. President Obama and the Democrats have decided to run on the “tax the rich” mantra, while the Republicans have focused on what former Reagan economic advisor Larry Kudlow says is more “pro-growth, flat-tax reform.” Herman Cain has his 9-9-9 tax plan, Rick Perry has a flat 20% tax plan, and even Jon Huntsman has come out with a flatter tax proposal, with a top tax rate of 23%.
