He describes conservative elites:
Matthew Yglesias: The Red Menace: Conservative elites... are absolutely convinced that France and Germany are dystopian cesspools and that Scandinavia can no more exist than a round circle. If the government starts giving people health care and building trains, next thing you know we’ll all be... well, it’s not clear exactly what we’ll all be like. But it won’t be good!
Either this is a deep and subtle claim that conservative elites are so batshit wingnut insane that it is as if they deny the existence of a round circle.
Or this is the world's worst typographical error.
