Clinton needs 100% of the remaining white vote to catch Obama
She has 1426 pledged delegates. There are 217 unpledged.
She needs 201 (93%) to get a majority (1627) of pledged delegates.

If black votes comprise approximately 10% (22) of the remaining 217 delegates, then she needs to win 100% of the remaining white and hispanic vote (193 delegates)and... and hope that 36% of blacks will vote for her (8 delegates).

But Obama gets 92% of the black vote.
