With friends like these, we do not need enemies. Mitt Romney made no such dial back, did not raise or lower expectations, did not change his policy. This is what did happen.
Romney gave an intelligent, responsible and mature discussion of his tax rate reduction proposals which he in no way dialed back. He is also the only candidate who isn't hyping or lying or fomenting class warfare on this.
He reminded people listening that he also proposed in the same plan a closing of loopholes for businesses, and a reduction in deductions which will hit personal tax returns. And more likely the reductions in deductions will hit out at $100,000 and up. A reasonable inference is also that some under $100,000 will see some deductions lowered.
