Mismanaging the Media?
As facts emerge, they may be right; that being said, it seems that faulty handling of the media in the early days of an administration is a pattern we saw in the Clinton White House that is now being repeated here.
If there is a systemic disadvantage for Democrats, it rests in the fact that their presidential nominees receive an easy ride from the press during the general election season. Then, as they assume power, they expect the same treatment to continue, not realizing that the press has to write about something.
I've argued before that there's real reason to believe that the press won't ever really take on an Obama White House -- at least, not with anything approaching the vigor and ferocity that the Bushes and even Clintons (at last) faced. That being so, it's a pretty remarkable show of ineptitude if the Obama team is mishandling the press and thereby drawing criticism from liberals like Powers.
