Many of the commenters point out that the information landscape has changed. The MSM isn't the only, or even the dominant, source of news as it was during the Vietnam War. There is Rush Limbaugh and his legions of imitators on talk radio; there is Fox News Channel, and there are the hundreds of weblogs out there, all working to ensure that the Conventional Wisdom
It's been a long-standing article of faith in the Republican Party that the MSM tilts heavily to the left, and in just about every libertarian or consevative blog you can find posts alleging or demonstrating how not only the opinion but the news pages of the local fish wrappers are biased against the GOP and those who vote for it. One of the reasons Ronald Reagan is so remembered as a hero is that he treated the MSM with amiable disregard, going over their heads to speak directly to the American people about issues he felt were particularly important. Along the same lines, W seems to have taken a page from Reagan's playbook and has gone directly to the people both in speeches and through the blogosphere, though his disdain of the press is quite clear. (To be honest, if I had to deal with a senile, raving moonbat like Helen Thomas, I'd probably do the same.) Bay thinks this is a mistake, but...I have to wonder. Despite the embargo on good news coming out of Iraq and Afghanistan, nonetheless the word does manage to get out that our troops are accomplishing great things in both countries, and the locals are picking up the burden of rebuilding as well as taking on the task of internal security. There is a hard core of anti-war protestors, but the Silent Majority that supported Nixon against McGovern in 1972 isn't so silent any more. So maybe W's dismissive, possibly even hostile attitude toward the NYDCLA press is working after all. It's possible that the MSM may be realizing that they can't survive playing the same old obstructive partisan games, and changes may have to be made.
Considering the success of Fox News, it's amazing more of the press hasn't realized that there's quite a bit of money to be made in serving up less bias with the morning dose of newsprint.
