America always has had strange outliers on the margins of our politics, from half-secret movements like the Know-Nothings to the left-wing crazies of the late 1960s. My eighth grade teacher referred to those on the farther shores of our politics as the “lunatic fringe.”
In more recent times, most of the nuts have been right-wing nuts. When I was young they opposed putting fluoride in the water, seeing that as a Communist plot. Indeed, they saw Communist plots everywhere. The head of the John Birch Society wrote a book claiming that President Dwight D. Eisenhower was an active agent of the Communist conspiracy. Asked about this once in Hillsdale, William F. Buckley Jr., said Eisenhower wasn’t a commie, but a golfer.
Well, classic communism is gone. Nobody talks about fluoride any more. But we still have a conspiracy-haunted fringe, and in Michigan today their latest cause is fighting what are called the Common Core Curriculum learning standards.
