This book was a really great overview of the rise of evangelicals in the states and their influence on the Republican Party. 
I found the authors critic of the patriarch to be very interesting. 
The only major flaw I found with the book is that it talked about some conflicts as a given. I am pretty well versed on Vietnam, Korea, Afghanistan, and the second gulf war, but didn’t really have enough information about the first gulf war to understand what was going on.
