I've been perplexed by much of Obama's presidency. While I was never a supporter his relationship with his base has been hard to fathom, Mr. Klein has provided useful clarification. This book deals almost exclusively with Obama's actions as President, and relationships with supporters. I've read other material concerning Obama, much about his unusual personal narrative or future plans.
This one, while not always attributed (sometimes for obvious reasons) deals with the Obama's disdain for politics which has often limited his effectiveness at pursuing his agenda.
