Of course Cruz is their choice. Either before the nomination or before the election, they can go to a compliant judge and hold his Natural Born Citizenship up in courts. If it happens before the nomination, the backstabbers can steal the nomination. If it doesn't happen until after the nomination, it hands the election to hillary.
Those who think it won't happen must trust the backstabbers. That would be the same folks who stole the nomination for Cochran.
Idiots or complacent? It's one or the other.
