Here's the math for the 3 remaining

Delegates	Count	% of remaining 
available	1079 
needed 		1237  

trump has	661
trump needs	406 	(38.6%)
cruz has	406
cruz needs	831 	(77.0%)
kasich has	142
kasish needs	1095	(101.5%)

Cruz's chance of winning is half of Trump's chance.

Kasich's chance is worst than zero and requires many more delegates than the 1,079 remaining.

In short Cruz is running against the wind and Kasich is running to steal it from the voters at the convention.

Trump needs 54% of the remaining delegates.

Upcoming primaries, through April. Could be rough for Cruz and Kasich.
