You keep using Iowa, but nobody think Cruz won that race fairly and that includes people in New Hampshire and South Carolina among others. Cruz isn’t even winning in South Carolina and that is his state. He is damaged from his lack of integrity.
He won it completely fairly.
As far as South Carolina being his state, not sure what you mean by that as Senator Cruz is from Texas.
I’m guessing you mean its a strong evangelical state. As Iowa CLEARLY showed, Donald’s numbers are fluff when it comes to polls vs. actual votes.
