The perfect outcome is if somehow the Dem nomination battle ends up in the Supreme Court..
Would be great, but will never happen, other than HRC challenging a re-vote in FL and MI.
They will work this thru by convention time, but in the meantime, Hillary will do the work "that Republicans don't want to do," and hopefully, bloody B.O. enough to make him vulnerable, should he prevail.
Personally, I believe that both have such big egos that neither would want to accept role as VP.
