Cruz is still a Canadian citizen. Carson would do what Herman Cain should have done: make it mathematically impossible to lose. Cruz and Carson have different styles, and Carson is, in my opinion, the style we need for wider appeal to sell certain ideas (yes, we need to convert some demo rats).
Don't mistake me, I love me some Cruz. But I want the sure thing.We cannot afford to lose next time. The demographics are not in our favor.
