President Dwight Eisenhower said that in our system of government, politics needs to be the part time occupation of every citizen. Ben Franklin, when asked what sort of government we'd been given, as he was leaving the Constitutional Convention after the final session, said "A Republic, if you can keep it."
This book should be required reading for all who take their job as citizen seriously. This year there has been a resurgence of interest in our common part time job, and it should make the 2012 elections very interesting.
If you, like me here in Colorado, are in one of the 17 states or so that has a caucus-assembly system for selecting your presidential nominees rather than the primary that most states, unfortunately, now use, this book will help you understand the process better and help you to be a more active participant.
If you are in a primary state, maybe it will inspire you to work towards restoring the caucus-assembly system where you live, the system that is the full flowering of the representative democracy our founders gave us, in my opinion.
