Columnist Paul Krugman is relieved the news media is finally waking up to Republican "extremism" in Monday's "Going To Extreme ." (I question Krugman's analysis: Times editors like Sam Tanenhaus  certainly aren't shy about throwing the term "extremist" around when it comes to the Tea Party movement.)
Krugman used Sen. Bob Bennett's recent defeat in the Republican primary in Utah as his launching point:
Utah Republicans have denied Robert Bennett, a very conservative three-term senator, a place on the ballot, because he's not conservative enough. In Maine, party activists have pushed through a platform calling for, among other things, abolishing both the Federal Reserve and the Department of Education. And it's becoming ever more apparent that real power within the G.O.P. rests with the ranting talk-show hosts.
News organizations have taken notice: suddenly, the takeover of the Republican Party by right-wing extremists has become a story (although many reporters seem determined to pretend that something equivalent is happening to the Democrats. It isn't.) But why is this happening? And in particular, why is it happening now?
The right's answer, of course, is that it's about outrage over President Obama's "socialist" policies - like his health care plan, which is, um, more or less identical to the plan Mitt Romney enacted in Massachusetts. Many on the left argue, instead, that it's about race, the shock of having a black man in the White House - and there's surely something to that.
But I'd like to offer two alternative hypotheses: First, Republican extremism was there all along - what's changed is the willingness of the news media to acknowledge it. Second, to the extent that the power of the party's extremists really is on the rise, it's the economy, stupid.
So why has the reporting shifted? Maybe it was just deference to power: as long as America was widely perceived as being on the way to a permanent Republican majority, few were willing to call right-wing extremism by its proper name. Maybe it took a Democrat in the White House to give some observers the courage to say the obvious.
