If the current pattern holds (and it may not. The IA caucuses and NH primary are far from representative of the remaining 50+ state and territory races) Sanders will end up with a plurality of delegates but not a clear majority. Unless a bunch of people drop out, the other delegates will be scattered among several so-called "centrist" candidates, who are all anti-Bernie. So the likely outcome (again only if the current pattern from non-representative states holds) would be Sanders forcing the Democrats into a contested convention, which will immediately pick someone else to be the nominee.
That's the irony surrounding all the vitriol I see online from Sanders supporters towards Warren. I guess they "snake" Warren and harass her supporters because they see Warren as a rival for the same votes. But Warren delegates might be the only delegates who would go to Sanders over Bloomberg (or whoever) in a contested convention. If Sanders goes into the nomination with only a plurality, he needs a candidate with her own delegates who might consider moving to the Sanders camp after the first ballot. To win the nomination in a contested convention scenario, Sanders needs someone else to bring more progressive delegates into the convention.
