For two years, expect all myth, no man, besides some information on the latter. The real Reagan and his "Revolution" is no "shining city upon a hill whose beacon light guides freedom-loving people everywhere." Nor is it "morning in America....Prouder, Stronger, Better," the stuff Madison Avenue or Hollywood moguls dream up, making molehills into mountains. Reagan revisionism will make him Everest over a stomach-churning two years. You've been warned.
