I figured Edwards had a card to play at the right time, he's spent the last six years angling for the Presidency, and he's seen the Beest overtake his lead in Iowa. If Republicans had the goods on this story, they'd never even breathe a word of it now, it would be much more effective as an October surprise.
As much as I want to believe that somebody finally has the truth on this, I remember being led down the Danny Williams primrose path a few years ago...
Republicans would be as avid to keep it quiet as the Clintons probably are. Republicans have historically been as determined to cover up Democrat scandals as any Democrat.
