If you believe 5-38's assessment, you can see
on their pretty brilliant presentation (if the data is equally brilliant remains to be seen) they think that at this point, Hillary needs 682 delegates to be on target, while Bernie needs only 639 to be on target. Hillary is overachieving at 113% right now, but their assessment means
that the road gets friendlier for Bernie in the future. Add momentum. This is not over by a long shot.
Similarly you can see by the targets for the Republicans how toast Cruz is already (again if 5-38's projections are near accurate), although he only has 100 delegates less than Trump. Because he would need almost 100
more delegates than Trump at this point given that many of the rare places where he can impress with his fanaticism already have voted.
