Task: Sentiment Analysis
Input (English): 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
Output (English): POS
