Just ordered it today, actually.
I wrote a review on Amazon for that book, it was so good I read it twice.
Most timely book of our time.
Goes beyond Richard Neuhaus “The Naked Public Square: Religion and Democracy in America” which itself was a book for its time in the 80’s and 90’s. Since that time we are becoming nearly banished from the public square and our influence for the culture.
