Cruz should continue to campaign in New York and surrounding states until he sells them on his great charisma. I feel a breakthrough in the making. And while I'm talking strategy, I have another suggestion. Lindsay Graham should keep doing TV interviews so he can explain that he supports Cruz because that's the way to save the Republican Party from its voters. And how his friends in the Middle East are really, really afraid of a Trump presidency.
Glad to help. <^..^>
