Here is a link from the very pro-Trump Brietbart:
If Trump knocks it out of the park from here on, he’ll fall short 50-100 delegates.
The more likely scenario is 200 or so, with Cruz breathing down his neck.
Again, it will be a contested convention, like it or not.
Has nothing to do with being a Cruz or Trump supporter.
It’s just a fact.
It's pretty good.
I've personally thought he might be short between a handful and a hundred, but also thought it more probable that he gets over the mark.
As far as Cruz breathing down his neck, he'll be somewhere between 700 and 800 at best. That's NOT a tremendously strong position. It's a distant second.
I will say something you may not like: If Cruz were to prevail in a contested convention, one where Trump is barely short and Cruz is close to six hundred short, the GOP might as well say president Hillary right now, because it's going to lose in a landslide.
