Matt Bai observes the revolving door between media and public service:
Now it seems that Cronkite’s brief moment as a vice-presidential contender may have been the first inevitable step down a treacherous path. Today we’re not at all surprised to hear names like Chris Matthews and Lou Dobbs tossed around as candidates for higher office. And while it used to be that only political aides of notable talent, people like Bill Moyers and Pat Buchanan and George Stephanopoulos (and, well, Chris Matthews), could make the tricky transition from politics to TV news, now it’s the politicians themselves Joe Scarborough, Mike Huckabee who find themselves ensconced as hosts on a cable-TV set. The door between politics and television news now isn’t merely revolving; it spins so fast and so continuously that a fair number of people no longer seem to belong neatly on one side or the other. Is Sarah Palin, at this point, a politician, or is she the star of some “frontier family” reality show? In fact, she seems to realize that the changed environment allows her to be both at the same time.
