I recently read that bio. Two great passages in it:
Chapter 11, A Populist Gentlemen's Club, p. 246:
The North and Midwest viewed the Southeast as the most backward part of the nation, the most resistant to change, and the most out of step with postwar realities. Southerners viewed the Northeast as economic exploiters and racist hypocrites.
Chapter 39, Tet, p. 818:
Reform is rare and difficult in the United States, a deeply conservative country.
