First let me state that if GOPers had any sense at all, they would have backed Kasich as the most moderate and sensible of the remaining candidates
Yes, well we've all seen how well the GOP has done with moderates and RINO's the last few elections.
The definition of insanity................
But the GOP Establishment is perfect at manipulating the dunderheads into playing into their tricks and traps every time.
Cruz will not get the nomination. He is a spoiler for the Establishment choice and who knows who that will be.
In this race, Kasich is the closest thing to the establishment as they can get. So if they want to upset the apple cart, they will nominate Kasich which is why he's still in the race.
Trump and Cruz can't be controlled by the establishment or anybody else for that matter. Kasich will bark like a dog anticipating a cookie for doing as he's told. That's what the establishment wants.
However, by making such a choice, they face the destruction of the Republican party for many years to come. Trump voters will change parties to Independent or Libertarian, somebody may start a new party, the TP could be reactivated.
But everybody has a chance supposedly. That's why these candidates "suspend" their campaigns instead of just quitting. Yes, it's a lottery ticket, but a ticket worth holding.
