Ohio didn't vote yesterday. It's governor refused to abide by a court decision and used the excuse of the election being a public health hazard. He cancelled the election, saying it would be held later (possibly in June).
But the other states voted -- Florida, Illinois, and Arizona. And Joe Biden scored huge victories in all three states. He won Florida by about 39 points, Illinois by about 23 points, and Arizona by about 12 points.
That gave him most of the available delegates in those states, and he increased his delegate lead from about 150 to nearly 300.
It looks like Joe Biden is going to be our nominee. But I still don't think Bernie Sanders should be pressured to quit. Let him make that decision in his own time, and don't give his supporters the idea they were not allowed to have their say.
