The tree of crazy must be refreshed from time to time by the Kool-Aid of birthers and deathers

As much as I admired Rick Perlstein’s Nixonland and his book on Goldwater, his Sunday WaPo article on how “the crazy tree blooms in every moment of liberal ascendancy” makes me hope his next book will be on that very subject, taking a longer chronological view than the earlier books. 1917 to present?
