Mostly unsubstantiated rumour
This was the most reputable reaction/coverage that I could quickly find.
Most of the other stuff was tabloid or blog stuff.

The National Enquirer article is quoted (if you really need to read it).
"This is the National Enquirer we’re talking about here, not the Washington Post. Then again, as Byron York points out, “the Rush Limbaugh oxycontin story was broken by the Enquirer, and the press ran with that one.” Indeed, the Enquirer breaks legitimate scandals all the time. But they run with all manner of nonsense too — they just don’t care so long as they sell papers.
I discovered the story via a spate of referrals to my previous post on this, “John Edwards Love Child Scandal” (see it for back story) and was going to relegate it to Gone Hollywood until I saw that it had reached Memeorandum. As with traditional media (and Pajamas Media!), the fact that a story is being covered elsewhere makes mere rumor necessary to cover.
Edwards has been widely touted for another run as vice president, although I can’t see why he’d want to go through that again, especially with his wife in ill health. Certainly, those facts would make the scandal worse, if true. Frankly, I hope it isn’t."
On the plus side, I did find out Estelle Getty has died.
