The Krugman (boldface mine):
No, this story is all about the G.O.P. First came the southern strategy, in which the Republican elite cynically exploited racial backlash to promote economic goals, mainly low taxes for rich people and deregulation. Over time, this gradually morphed into what we might call the crazy strategy, in which the elite turned to exploiting the paranoia that has always been a factor in American politics — Hillary killed Vince Foster! Obama was born in Kenya! Death panels! — to promote the same goals.
For reasons that range from ‘I agree with the backlash’ to ‘my friends/’sources’ would never cynically use bigotry’, a central failure of governance (which is different than government) has been the news media’s inability and unwillingness to identify bigots as a key Republican constituency which is pandered to by Republicans.* Now that the cover for overt bigotry is transforming into ideology (the ‘crazy’), Democratic leaders have decided we’re ‘moving forward, not looking back.’ There will be no accountability for this, so the next generation of Republicans will not have to face the consequences of their rhetoric.
*Chuck Todd’s whining notwithstanding, exposing the underpinnings of why people think what they do even when they would prefer you not to do so is a key function of journalism.
