The reason for a lot of the double standards in place here is that the MSM is trying to counterweight the power of the White House, even if the White House isn't in the wrong.
The Valerie Plame issue versus the wiretap one is a perfect example. It's not the facts of the matter they care about. It's that they feel helpless against Bush, and they're willing to twist the truth as far as need be to restrain him. They genuinely feel that he is a greater threat to their interests then Al Qaida, and view everything through that warped lens.
Wow. You just nailed it. Something just crystalized for me. The American Left are POLITICAL ACTIVISTS first and American Citizens some where way down the list of their priorities.
