Just my 2 cents worth but Edwards is a rich Trial Lawyer and now that he has a taste of power he probably will stay in it til the primaries and the nomination are over..He may see himself as a VP candidate if Billary decides not to select Obama or Richardson...Richardson is out of the running, keeping his millions intact but until he endorsed Obama he seemed to be a lap dog for Billary...
Richardson has denied endorsing Obama in the delegate caucus in Iowa, despite numerous reports to the contrary. Now he's saying he's not endorsing anyone until after February's super Tuesday which means he's trying to make nice with the witch-b*tch. Also, some of his campaign staff have joined with Hillary, more than went to Obama.
