A Sixteen-Year Political Cycle?

Calvin Trillin, in his essay “The New, New Right” (quoted here in a different context) noticed that conservative political activism tends to revive every sixteen years. At the time, that was limited to 1946, 1962, and 1978, but it has continued with 1994 and 2010. Will the pattern continue?

There's a possibly-associated phenomenon. Six years after the revival, it goes awry and is hijacked by a moderate and/or a crackpot. (Moderates: Eisenhower, Nixon, Bush the Younger, and Donald Trump. Crackpots: Joseph McCarthy, George Wallace, and Donald Trump).
