Cruz will be mathematically eliminated after NY.
Surely you must know better than that. If Trump doesn't get the requisite delegates, then he is just as mathematically eliminated on the first ballot as Cruz is. And that is why it is worth spending time and money in NY to keep Trump under 50%. If that happens, there is almost no chance Trump can get the delegates he needs to win the nomination - and believe me, Trump WILL lose on the 2nd or 3rd ballot. You run a sleaze campaign full of insults, lies, bullying, etc, and Trump will reap what he has sewn at the convention.
