The Sanders narrative is simple: 
 
- If Hillary won a state, it was rigged, she bribed state officials, tampered with machines, etc. So really, Bernie won. 
- If Bernie won a state, it was holy and virtuous and oddly HRC decided not to rig those machines.
- If there is a tie, Bernie won.
- If it is close, Bernie won.
- No matter what the vote count is, Bernie has more.
- Superdelegates are only allowed to pledge to him, Hillary is banned from receiving Superdelegate support because they are all corrupt and bribed if they pledge to her, and again, holy and virtuous if they pledge to him.
- Anyone not declaring Bernie to be the only choice was paid off. So really, Bernie won.
