You know Democrats have no winner-take-all states, yes? The longer it drags on, the higher margins Bernie has to win by to overcome her delegate lead. He's going to blow her out in New York and California? So Bernie has closer to a 7% chance than a 70% chance of being the nominee.
The GOP is less certain but Trump is not unacceptable to the majority of Republican voters. A record number of Republican voters for a nominee? Yes. A majority of them? No. They might still stop him but he's much closer to 90% to win than 90% to lose.
He'll win a lot of states from Wisconsin to Washington to Oregon, etc which are delegate heavy & a lot of smaller states after today - All these by good margins.
New York looks impossible but California looks possible for a win, maybe a decent win (not blow off) considering we have absolutely an army of passionate Sanders supporters, it's unreal!
