Q: The Presidential Difference . This book offers insightful, thorough, and well-reasoned analysis of every modern president, from FDR through Clinton, all in slightly more than 100 pages. Greenstein concisely but comprehensively reviews all of these presidents based on various categories -- from charisma to cognitive abilities to emotional maturity. Beyond that, he provides a historical backdrop to each presidency, providing context and texture for each tenure. This book offered fresh perspectives to most every presidency, and forced me to reevaluate the Bush and Ford presidencies in particular. I imagine most readers will find that Greenstein's book challenges many of their long-held assumptions too
A:
POS
