They never really covered the Edwards story. I mean the allegations were out there, and the mis-information was put forward and that was the end of it. It was only his stupidity in visiting her, and the crack reporting of the Enquirer that led to widespread disbelief in his story.
An interesting aside I have heard that he was 'outed' by campaign staffers who realized that if he won the nomination that the Dems would lose when his love child was revealed. Essentially they put party loyalty over personal loyalty.
If Obama is sick we'll hear about it when he has to go in for a long stay at the hospital, and it will be claimed it was all just discovered Tuesday.
As for past (or present) sexual indescretions - I doubt they will ever report those. Only Republican's have their sex lives investigated by the MSM. (Remember the bogus McCain affair rumors the NY Times put on their FRONT PAGE!).
I will say that the Globe printed an unending list of similar stories about Bush, and I believe they were mostly slander. So all joking aside I can't take anything they say too seriously.
Now the Enquirerer, that's who broke the Edwards love-child story. They seem to have a slightly better track record.
I remember reading a Globe story about bin Laden. According to this story, bin Laden hates the US because an American women ridiculed him as sexually inadequate. About 3 weeks later the building with the Globe offices had an anthrax attack which killed one or more people, I don’t remember the details, but I remember thinking at the time that it was bin Laden retaliation against the Globe. Never heard that suggested in the news.
