Restoring American Exceptionalism” has recently become an important Republican slogan. It’s a featured theme for Newt Gingrich, Rick Santorum, and Glenn Beck. Mitt Romney and Ron Paul at least bow in its direction, as do Rick Perry and Sarah Palin. Last month, there were hundreds of “Restoring American Exceptionalism” events during National School Choice Week (Jan. 22-28, 2012), under the leadership of the Americans for Prosperity Foundation, founded by David H. Koch.

The odd thing about this is that “American Exceptionalism” was originally a Communist doctrine motivating a moderate and reformist approach to revolutionary organizing, developed and fiercely argued in the 1920s and 1930s; and the term was revived, with a similar meaning but a different motivation and emphasis, by liberal political scientists in the 1950s.
