I don't think this has anything to do with Limbaugh being a conservative. You think Wilma wouldn't have pulled the same stunt on one of the Kennedys? (Of course, if she had they would have paid her off.)
It's more than "allegations". As I said, there appears to be audio-taped evidence, email evidence and polygraph test results (though I think OJ once passed one of these so that doesn't say much...)
Limbaugh's lawyer asked her to hand over her computer because he was worried about the email fingerprints being on the machine - as happened with Lewinsky. Instead, she took in a hard drive from another computer to his office and destroyed that in front of him.
It isn't more than allegations. There "appears" to be audio taped evidence? What does the audio tape say? Who is saying it? What kind of quality is it? Have the voices been authenticated? The e-mails (at least some) were published. How do we KNOW that the e-mails were written by Rush? Did she have access to Rush's computer? The grammar, from the quotes I've seen on FR, is fairly sloppy. Who said they took a polygraph? Who gave it? What were the questions asked? Who interpreted it?
The media can say anything they wish. All things reported are not true.
