I’m often confused when I do some simple math on poll data. According to this poll, for example, Only 32 percent said they were satisfied with how Bush is handling his job and only 21 percent said they believe things in the U.S. are heading in the right direction. So 32 minus 21 … Does that mean 11 percent are satisfied with heading in the wrong direction? Is there an alternate reading of these numbers I’m missing? If not, what is wrong with those eleven percent?
