It's from a post by Ezra Klein arguing that it's a shocking revelation that Obama is, in policy terms, like a centrist Republican from the early 1990s. Since I've been essentially making this case for a few years now, this does not shock me. I remain of the view that president Obama is the best conservative president since Bill Clinton.
