Not quite accurate.
A poll of the membership recommended that the leadership of the party (the National Political Committee, NPC) endorse Bernie. However only about 13,000 people voted and there are 40,000 dues paying DSA members. It's not clear whether the low turn out was because of lazy millennials or because of a boycott by more radical DSA members who don't think the NPC should to choose (and who generally don't favor Bernie).
The NPC will decide on March 21st whether or not to endorse Sanders.
They probably will. The NPC is much more moderate than the org at large. The org at large is made up of people who consider themselves Communists, many oppose Bernie for not being "a real socialist" and for his past comments about open borders being bad. The NPC, on the other hand, is tenuously controlled by the social democratic "Momentum" faction, which is closely linked with Jacobin magazine and likes Bernie.
Their control is tenuous though. Not all members of Momentum are as moderate as Momentum's leadership. If enough Momentum NPC members defect to the minority "Praxis" faction, they could block an endorsement and then the DSA won't endorse until their annual convention.
If Bernie could win at the DSA national convention is not entirely clear.
I say there's a 75/25 chance the NPC endorses him on March 21st and if they don't, a 50/50 chance he wins the endorsement at the DSA national convention.
