Trump will probably take Ohio too, so your count is off.
Trump will get the needed 1237, or pretty damned close to it, on April 19th. !
NY, Ill, Ct and N.C. are not WTA. Trump will likely split these delegates. PA requires Trump win 50% to get all the delegates. NJ is on the same day as California. Trump needs over 700 more delegates. Not going to happen without California and Ohio. He’ll get more than anyone else. But this race is going to the convention without running the table on the big WTA states.
