From Dana Milbank's upcoming column in the July 18 Washington Post:

Twenty years ago, the dawn of the Internet Age gave us Godwin's Law: If an online argument goes on long enough, somebody will eventually invoke Hitler. When that happens, it's basically the end of the conversation, because all rational discussion ceases when one side calls the other Nazis.

These sentiments have long existed on the fringe and always will. The problem is that conservative leaders and Republican politicians, in their blind rage against Obama these last 18 months, invited the epithets of the fringe into the mainstream. Godwin's Law has spread from the chat rooms and now applies to cable news and even to the floor of the House of Representatives.

Consider these tallies from Glenn Beck's show on Fox News since Obama's inauguration: 202 mentions of Nazis or Nazism, according to transcripts, 147 mentions of Hitler, 193 mentions of fascism or fascist, and another 24 bonus mentions of Joseph Goebbels. Most of these were directed in some form at Obama -- as were the majority of the 802 mentions of socialist or socialism on Beck's nightly “report.”
