Spoke Larry Kudlow and James Taranto, WSJ, re the Herman Cain aggressive tax plan, 9-9-9, and learned that Steve Moore now believes that the Cain plan is badly flawed. The 9% sales tax is wrong. The criticism by Mitt Romney in the Las Vegas debate was accurate. The national sales tax added to the state taxes, without deductions, will mean that the taxes for the majority will rise. Steve Moore told this to Larry on Saturday, and said he would pass on the facts to Herman Cain (Moore is an advisor). However, after tonight's debate, it appears that Steve Moore did not reach the candidate for the correction; or, if he did, Cain did not heed the warning.  The adjustment makes this plan unlikely, since it would now be 9-9-0-plus.  The pummeling Cain took on 9-9-9 may be the end of his boom.  Cain is popular and nimble.  The adjustments of the plan will require footwork.  Will Cain bother?  Mitt Romney ignored Cain in order to trade fisticuffs with Rick Perry.  This was Perry's best debate by far, though he did not persuade that he is ready for the election.   Mitt Romney remains the man for all platforms, the best-disciplined and most-resourceful character to face off with POTUS.  Romney is not exciting, fast or convincing.  However, POTUS continues to run against the GDP, not the GOP, and the bank earnings disappointments point to continued uncertainty in the regime.  Romney's best case is that he respects markets and will promote growth, not class grievances, nor gender, nor religious and regional prejudices.
