Perhaps Sanders doesn't feel like he has lost yet.
But even if he does think he has lost, by continuing to amass large numbers of delegates, he ensures that he is a natural second choice if Biden self destructs.
Alternatively, he could refuse to withdraw until the Democrats agree to adopt some of his ideas as part of their party platform.
But ultimately, why does there have to be any good purpose?
Withdrawing and conceding is for when you are defeated by someone worthy of respect. I do not agree that progressive candidates are worthy of respect.
I think that when people lose to a progressive candidate (and this includes when two progressives run against each other), the loser should stay in the race to the very end and mount as many recount demands and legal challenges as possible just to delay things. And then after they've delayed things as much as possible they should just walk away without conceding or acknowledging that the other guy won.
