This is what leftists do. It doesn't matter that the website is simply reporting what was said to authorities, and it doesn't matter whether the information is true or false. All that matters is defending their guy, because he's one of Them. (For "leftists" above, you could substitute "lawyers" with the same result ;-).
If I'm surprised at anything, it's that John Edwards still gets any support even from leftists. He's such a loser, such an embarassment ... and he's white.
Some people are considered under the law as “defamation proof”; in other words, they have such bad reputations nothing you can say or write about them can injure them. I wonder whether Edwards could be considered “defamation proof” since he is both a lawyer and a politician neither of which are held in high regard by the public as a general matter.
