As I rarely parse an Obama speech and I never watch Fox news (not getting it and other cable news in my basic cable package, so I have no idea who Glen Beck is), maybe I can offer some unprejudiced insight into the recent contretemps. Krauthammer attempts a principled objection--though he misses the point about Madisonian factions: Factions are not "legitimate"; they are by definition unjust groups, who misuse the fundamental commitment to liberty. So the real objection to Obama's shunning of Fox (he spent a couple hours before a group of leftist journalists dismissing it as "talk radio") is his assault on liberty--his misunderstanding of the freedom of the press.
For all their leftist inclinations, a significant number of journalists don't want to be known as anyone's stooge. The Fox infection will spread quicker than the swine flu.
As evidence see the NY Times on Fox's effect on the MSM:
White House officials said [...] they noticed a column by Clark Hoyt, the public editor of The Times, in which [leftist Clarence Thomas hater] Jill Abramson, one of the paper's two managing editors, described her newsroom's "insufficient tuned-in-ness to the issues that are dominating Fox News and talk radio." The Washington Post's executive editor, Marcus Brauchli, had already expressed similar concerns about his newsroom....
"This is a discussion that probably had to be had about their approach to things," [Obama political strategist David] Axelrod said. "Our concern is other media not follow their lead."
In fact, perhaps the most effective media purveyor of conservatism (next to Rush and Fox) is C-Span radio and news. (Have I let the cat out of the bag?) For without its coverage of otherwise obscure think-tank speakers and panels, many eminent conservative voices would get no significant hearing at all. And their book programs may be the best thing on tv (save the excellent baseball playoffs this year).
