The most important job of the media is holding the powerful accountable. This task, I believe, is why the founders put the freedom of the press in the First Amendment.
That's why it's upsetting when the media abets deception by politicians — and that's exactly what the major media has done with regard to Obamacare.
One purpose of Obamacare was outlawing health insurance plans that didn't meet the standards of President Obama or the drug lobby. Yet when Obama said, again and again and again, "if you like your health plan, you can keep it," the media largely treated it as something that was either true, or at least an intended effect of the law.
What happens when it becomes clear that you can't keep your health insurance, and that Obama knew that and even intended that?
The Washington Post oddly writes that Obama has been "accused" of breaking a promise. And then the New York Times laughably writes, "Mr. Obama clearly misspoke when he said that."
This isn't merely a matter of liberal media bias. This is dereliction of duty. Apologizing and covering up for the President when he lied is doing the opposite of what the media is supposed to do. And it encourages future politicians to lie — because as long as you insist the other side is wrong, the media is now drawn to cover your argument as if it's plausible.
