Cruz and Kasick have no change of winning the delegates needed to win the nomination. Both are only in it to stop Trump from winning so that the GOPe can give the nomination to a true and trusted GOPer like Ryan, Mitt or Jeb.
Kasick is not going to win the nomination and should drop out. The Cruz odds are looking slimmer after last night.
The delegate numbers:
Trump 656 (has won 47% of allocated delegates)
Cruz 408 (29%)
Rubio 172 (12%)
Kasich 138 (10%)
Trump needs to win 55% of remaining delegates (including 60 left from last night) to reach 1,237 magic number
Cruz needs to win 79% of remaining delegates (including 60 left from last night) to reach 1,237 magic number
Kasich needs to win 104% of the remaining delegates (including 60 left from last night) to reach 1,237 magic number
