A few metrics for "Western Tuesday."
Bernie is currently 1,171 delegates shy of the nomination. He needs 58.0% of all remaining pledged delegates to win.
A total of 131 delegates are up for grabs tomorrow. Demographically, Bernie is expected to win 74 of them, or 56.5%. If he does this, he will gain 17 delegates on Hillary (who is currently ahead by 321 delegates), and will need 58.1% of all remaining delegates in order to win the nomination. So his job actually gets harder if he performs as per his demographic advantage.
If he outperforms expectations, and wins, let's say, 85 delegates (or 64.9%), he will gain 39 delegates on Hillary, and will need only 57.5% of all remaining pledged delegates to win.
On the other hand, if he ties with Hillary -- let's say he wins 66 to Hillary's 65 -- then obviously he gains only one delegate on Hillary, and will need 58.5% of all remaining pledged delegates to win.
Either way, after tomorrow the pool of contests, which started with 50 states and 7 territories (including Democrats Abroad) will be down to 21 states and 4 territories.
