Trump is not running as a holier than thou evangelical Christian. Cruz is.
I challenge you to find one statement of Cruz claiming to be “holier than thou”. HE does say that in the political arena, you shall know them by their fruits.
Which is why Trump is winning.
The percentage of the American population that want a preacher as President is so small, it's not even worth considering.
Republicans have fallen into the religion trap for decades. It's about time we stopped it.
