That’s not happening. Cruz is not even competitive in FL. That’s 99 delegates. Then there is Michigan, Ohio where Trump will likely win. The caucuses end tonight. So does Cruz.
Kasich is strengthening right now too. That's going to be troublesome if Trump doesn't shore up his message.
The polls all had Trump winning in all 4 states. I believe they had him running away with it in La. and Kentucky. Polls have been off. Cruz may come out of this with momentum.
