From a September 4 post on MSNBC.com's First Read blog:

*** Remind us again how the media is biased...: Finally, here's one more thought about the entire controversy over Obama's education speech on Tuesday: Since the White House has said the text of the speech will be available for 24 hours before he delivers it and since they altered the lesson plan language, why is this still a controversy? The ability of the conservative media machine to generate a controversy for this White House is amazing. In fact, this is an example of a story that percolates where it becomes harder and harder for some to claim there's some knee-jerk liberal media bias. (Does anyone remember these kinds of controversies in the summer of 2001?) The ability of some conservatives to create media firestorms is still much greater than liberals these days. How effective is the conservative media machine? Just ask Van Jones...

Media Matters: From an October 10, 2006, washingtonpost.com chat with Building Red America author and former Washington Post reporter Thomas B. Edsall:

The conservative movement has been very effective attacking the media (broadcast and print) for its liberal biases. The refusal of the media to disclose and discuss the ideological leanings of reporters and editors, and the broader claim of objectivity, has made the press overly anxious, and inclined to lean over backwards not to offend critics from the right. In many respects, the campaign against the media has been more than a victory: it has turned the press into an unwilling, and often unknowing, ally of the right.
