Bring the Jubilee

I once read a book called Bring the Jubilee, which was an "alternative history" of the United States from 1864 to approximately 1930 about what happened after the South won the Civil War.
Now Lance Mannion brings us up to date:

As fast as they can the Republicans are erasing the Presidency of George W. Bush from their official history, just as they've pretty much written Richard Nixon out of it and written out Republican isolationism and pro-fascist sentiment in the years leading up to World War II. They still aren't sure what to do with Joe McCarthy. They'd probably like to make him a non-person too but that darn Ann Coulter is so cute when she talks about what a hero Tail-gunner Joe was you just have to think she has a point.
For going on seventy years the National Republican Party has consoled itself, sustained itself, and kept itself alive by telling itself and anyone who will listen an alternative history of the United States. In this alternative history the New Deal didn't do any good at all, the Cold War was fought and won entirely by super-patriotic Republicans, welfare not racism or systemic poverty destroyed the African-American family, anyway racism ended when Martin Luther King's birthday became a national holiday (alternative to the alternative: racism ended with the election of Barack Obama), the 1960s are the root of all evil, the hippies and the liberals lost the War in Vietnam, 9/11 was Bill Clinton's fault, the financial crisis was Bill Clinton's fault, Barack Obama is turning America into a socialist dictatorship.

If people who don't learn from history are doomed to repeat it, what are these people going to repeat?
