when there are only a little over 1,000 delegates left?
There are only 897 delegates left that are decided by primary contests. Not “over 1,000”.
And Sanders would have to win 589 of those 897 just to tie Clinton with regards to pledged delegates going into the convention.
By contrast Clinton only needs 309 of them to have the majority of pledged delegates going into the convention.
When it comes to total delegates, Clinton needs only 164 more to reach 2,383.
I think Democratic voters in the remaining contents can and should vote their conscience for their preferred candidate, but the math is what it is and nobody should be under any illusions that Sanders has a viable path to the nomination.
