The state that has a large minority population, when his best showing among AA has been 77/22 and losing Latinos nearly 2 to 1? A state that Hillary Clinton managed to carry in 2008 after the nomination was essentially over?
The issue is not how many states Bernie wins. If Bernie had lost every single state by 5% tonight he would have been in better shape than winning all 5 he targeted by the margins he did. Everything is proportional. There are no big states on the map where Bernie can hope to out pace Hillary. Even in Califnorai, if Bernie beat her by 20 points he would only net enough delegates to cut her current lead by 200 when she's up nearly 660 (pledged and super).
For Bernie to have a chance at a tie, he needed 469 delegates this evening. Without CO and MN allocated, he's currently at 145, although nothing from Mass, Co or MN have been awarded.
