I believe this is why Kasich is hanging around.
{tinfoil hat} It is hinted or implied strongly by the GOPe that after Trump and Cruz fall short of 1237, that Kasich will be the "compromise candidate" due to his 3rd place vote totals and enuff released delegates after the first ballot to put him over the top.{/tinfoil hat }
They may designate Kasich, but I ain’t voting for him.
