I would change this. He is not likely to win New York, and probably not Puerto Rico.
If he were to win all other states according to the chart before June 7, he would have to win CA&NJ by bigger margins.
The chart shows him winning 390 in April, which is not likely, although maybe possible. If he wins a majority of delegates (366 or more) it will be much closer. He would have to really outperform in May & June to get to 2026 if he only gets 366 in April. He could win MD & NY, but it is highly doubtful and he would only eke out really small victories in those two states if he were to win.
He will be destroyed by Clinton in MD which has a higher black population than SC!
Anyways at this point it is about getting the maximum delegates to exert maximum influence. It is even more important to project himself as the alternative and not an establishment appointed if Hillary gets a bad result in the email case, which is very much possible!
