The Republican Party Is Now in Its End Stages
We are living in a time of bad metaphors. Everything is fascism, or socialism; Hitler's Germany , or Stalin's Soviet Union. Republicans, especially, want their followers to believe that America is on the verge of a dramatic time, a moment of great conflict such as 1968—or perhaps, even worse, 1860. (The drama is the point, of course. No one ever says, "We're living through 1955.") Ironically, the
