Rick Perlstein in the Washington Post:
So the birthers, the anti-tax tea-partiers, the town hall hecklers — these are “either” the genuine grass roots or evil conspirators staging scenes for YouTube? The quiver on the lips of the man pushing the wheelchair, the crazed risk of carrying a pistol around a president — too heartfelt to be an act. The lockstep strangeness of the mad lies on the protesters’ signs — too uniform to be spontaneous. They are both. If you don’t understand that any moment of genuine political change always produces both, you can’t understand America, where the crazy tree blooms in every moment of liberal ascendancy, and where elites exploit the crazy for their own narrow interests.
In the early 1950s, Republicans referred to the presidencies of Franklin Roosevelt and Harry Truman as “20 years of treason” and accused the men who led the fight against fascism of deliberately surrendering the free world to communism. Mainline Protestants published a new translation of the Bible in the 1950s that properly rendered the Greek as connoting a more ambiguous theological status for the Virgin Mary; right-wingers attributed that to, yes, the hand of Soviet agents. And Vice President Richard Nixon claimed that the new Republicans arriving in the White House “found in the files a blueprint for socializing America.”
When John F. Kennedy entered the White House, his proposals to anchor America’s nuclear defense in intercontinental ballistic missiles — instead of long-range bombers — and form closer ties with Eastern Bloc outliers such as Yugoslavia were taken as evidence that the young president was secretly disarming the United States.
