I think that it is clear is something will be done to reselect delegates.
The options are a primary and a caucus, and neither the states or the DNC are willing to front for a primary, which would cost about $25 million, $10m for Michigan and $15m for Florida.
My guess is that its probably going to be a caucus, but you could fund the primaries with soft money, so theoretically 1 person could cut two checks to make it happen.
