Ed Conard's book Unintended Consequences is on The New York Times best-seller list, but it was hard to find at my neighborhood Washington bookstore, Politics and Prose, deep in what you could call Obama Country. That's too bad. Mitt Romney is running his campaign so close to the vest as to be nearly invisible. The theory is to disappear, leaving President Obama to run against himself and his record on the economy. So if you want to know where Romney is coming from, you need to read not only the Book of Mormon and clips from The Boston Globe and his tax returns, you also need to read Conard's technical but fervent paean to the folks whom the soon-to-be Republican presidential nominee reverently calls "the job creators." That is: America's wealthiest and yearning-to-be-wealthiest.
