My model for this was
- Bernie is stronger than Hillary according to live Internet polls and could surprise upset to get Dem nom.
- Hillary has yet to ride out Benghazi, emails and rep as Claire in House of Cards
- Biden could have drawn away Bernie support and helped Hillary get Dem nom.
- Bernie is too pink to win the general election
Based on that I thought DNC would play Biden as a Bernie spoiler and Hillary alternative if she flamed out.
This means we have non-zero chance now of a Bernie-Donald face-off. Interesting times.
