Paul Kengor, the author with Patricia Clark Doerner of The Judge: William P. Clark, Ronald Reagan’s Top Hand, informs John J. Miller that his subject is a true Californian, a rancher with deep roots in the West, whose life was transformed when he met Reagan in 1965 — the start of “a long process of [Clark] wanting to live at the ranch, wanting to work on the ranch, but Ronald Reagan constantly beckoning and calling him into different jobs.”
