Reagan revisited

During the apex of the Reagan presidency, I was growing up, not even remotely interested in politics. I have never read Richard Reeves previous work on JFK or Richard Nixon, but I intend to pick up his new book on the Gipper because of this quote:

"Like one of his heroes, Frankln D. Roosevelt, he has become larger than life. As Roosevelt became an icon central to American liberalism, Reagan became the nucleus holding together American conservatism. He is the only president whose name became a political creed, a noun not an adjective: "Reaganism."
