Blackmail by Rielle is my theory of this case. Edwards has been giving her money all along, ever since they first started dating. But it evolved from a sugar daddy relationship into simple blackmail. She threatened to destroy his hopes for the presidency, so he paid her. Later, when that wasn't enough, he was forced to meet her at a hotel at midnight to discuss some higher payments, or a lump sum payment to buy her silence on a long term basis. And somebody tipped off the Enquirer.
Probably a Clintonista. Obama was thinking of offering Edwards the VP spot as a reward for endorsing him in May (and effectively ending Hillary's White House hopes for this year). Or Hillary just thinks Edwards might be the VP pick. She made a deal with Obama when she "suspended" her campaign and she considers the VP spot to be her rightful consolation prize, so she (or one of her supporters) removed Edwards as a temptation for Obama to break his agreement with Hillary.
As for Rielle, she's kinda hot and very manipulative. As she saw Edwards and her meal ticket drifting away, she made up her mind to stay close, and went looking for a guy close to Obama to seduce.
It's all speculation, but 100% consistent with characters involved: Hillary's flair for the knife in the back by just leaking to the press, Obama's flair for broken promises and flip-flopping, and Rielle's flair for ... well, you know.
I haven’t been posting for a few days, behind on the ‘happenings’. Not sure what the situation is between Rielle and Edwards now. I see that she is bad talking Elizabeth in the press.
She has blackmailed, but if it’s his baby he will want to keep contact.
Hillary’s aides are furious, knowing that she would have won Iowa had it not been for Edwards and this story was still a secret then. Maybe Hillary’s sources are not as good at finding things as I thought!!
They are a bunch of cartoon characters and Obama wears horns.
