Forbes has a list of the top 25 most influential liberals in American media. For the most part it’s a pretty reasonable list. But I don’t quite understand the way that liberal is defined any more. Ariana Huffington is definitely a liberal in the contemporary sense, as is Ezra Klein or even John Stewart. But is Thomas Friedman really a liberal? Or Christopher Hitchens? It seems like we’ve reached a point in our political discourse where anyone who isn’t a conservative is considered a liberal.
