That’s about 200-250? Don’t think Cruz is going to get that in the remaining states.
I do know the number generally enough to think that Trump will get 1237. Lots of factors in play, but the picture is going to look different by the time California primary is conducted. Plus, by that time, the press will be openly talking about the "unbound" delegates, rather than talking about the "second ballot" delegates. The press is trying to establish a narrative of momentum (to Cruz) and weakness (to Trump).
