Simple solution to a difficult problem.  Whereas Clinton wishes to not disenfranchise her voters whilst totally disenfranchising Obama's voters. We need to fix this for the voters sake.  Sounds fair and balanced, right?  Let's play fair....(sorry Hillzilla). 

OK. Listen close.  Both campaigns  pay for a targeted poll of all  Florida  and Michigan Democratic primary voters.  You then include newly registered  Dem voters, and any Dem voters from previous primaries.  Sorry about leaving out republican voters from previous primaries.  All of the address's and phone numbers can be very easily had. 
Since Survey USA seems to have the best track record of correct polling, Let's put them in charge of a poll driven re vote or any number of variations of polling.  At the very least, we will find the will of the people and then can divide the delegates accordingly. 
     Not exactly perfection, but a fair solution to a problem that seems to defy solution.  It has a bonus of being cheaper and more logistically sound.  And it carries a bonus.  No Druggy Limbo crossover spoilers.
