Is the mainstream media ignoring the John Edwards story?

So is the mainstream media ignoring the John Edwards story?
Long story short, John Edwards, the one-time Democratic presidential hopeful and potential vice president running mate, was cornered by reporters a few nights ago coming out of an LA-area hotel after a rendevous with his alleged mistress and love child.
Why haven't you seen it or read about it?
The story wasn't written by the LA Times, or the New York Times or the Washington Post or even Fox News or CNN. No, this story came from - get ready - the National Enquirer. Yep. The Tabloid.
Stories about Edwards and infidelity have been around since last year when it was alleged he got a woman (the same women he met at the hotel) pregnant and then got another male to step up and claim paternity for the child.
It should be noted Edwards' wife Elizabeth continues to battle cancer.
The Enquirer has been on this story since last fall - see the link. No one else has picked up on it. Why?
The easy answer is because it is false or unverifiable. That's the easy answer. Not neccessarily the correct one.
What's strange is news media is usually at a frenzy when this type of thing hits - see disgraced Idaho Senator Larry Craig, former governors Eliot Spitzer, Jim McGreevey and Bob Wise or former Pres. Bill Clinton.
Poltical scandal - especially infidelity - has been around as long as politics. I think it's more expected than not.
The strange thing is no one seems to be picking up on this story.
By no one I mean mainstream newspaper papers and cable news networks.
Laugh if you want, but the National Enquirer, while it may not be at the forefront of investigative journalism, has on occasion broken similar stories.
How long before this one finally breaks the surface and picks up speed?
