Republican Candidates Feeling Pressure From Ron Paul

Rick Perry reveals flat tax plan:  Rick Perry is proposing letting Americans choose between their existing income tax rate or a new flat tax of 20 percent, part of a tax and spending reform plan that the Republican presidential candidate is dubbing "Cut, Balance and Grow."

"The goal of my 'Cut, Balance and Grow' plan is to unleash job creation, address the current economic crisis, while at the same time generating a stable source of revenue to address our record deficit and put our fiscal house in order," Perry, the governor of Texas, said at an event Tuesday in South Carolina.
