Now that Reagan's achievements and failures have become more obvious, it is time for a new nonpartisan appraisal of his leadership and its impact on the nation. That is precisely what John Sloan delivers. Sloan focuses especially on the questions raised in the highly polemical debates between conservatives and liberals concerning Reagan's economic policies. He gives equal time to both sides, showing how liberals were wrong in their predictions of gloom, while conservatives continue to grant Reagan more credit and status than he deserves.
