A sex scandal being deliberately kept under wraps by the news media?
Involving a Democratic candidate?
Anyway, it appears that something is brewing. Glenn linked both of the above, but I can’t find any news reports with real dirt or names. Here’s what Ron Rosenbaum said:

So I was down in DC this past weekend and happened to run into a well-connected media person, who told me flatly, unequivocally that “everyone knows” The LA Times was sitting on a story, all wrapped up and ready to go about what is a potentially devastating sexual scandal involving a leading Presidential candidate. “Everyone knows” meaning everyone in the DC mainstream media political reporting world. “Sitting on it” because the paper couldn’t decide the complex ethics of whether and when to run it. The way I heard it they’d had it for a while but don’t know what to do. The person who told me )not an LAT person) knows I write and didn’t say “don’t write about this”.
If it’s true, I don’t envy the LAT. I respect their hesitation, their dilemma, deciding to run or not to run it raises a lot of difficult journalism ethics questions and they’re likely to be attacked, when it comes out–the story or their suppression of the story–whatever they do.

Oh and it’s not John Edwards
Hmmm…
Am I allowed to at least ask whether it’s a male candidate?
