Obama regularly claims that his plan reduces taxes for 95 percent of taxpayers. The one hitch is that only about 60 percent of income earners pay taxes. The fact that Obama’s claim doesn’t add up and by definition has to be false is hardly remarkable. What is remarkable is that McCain has consistently let him get away with making the claim. This leads to one of two conclusions, either McCain is purposely letting Obama slide or that McCain, himself, doesn’t know the facts of the matter. I’m not sure which is less appealing to contemplate.
