Trumps is our only nuke. Cruz has already started backing down on what's "fair game" with Hillary and what is not.
Cruz would need to be brutally honest with Hillary... as in the biblical advice for addressing a fool. But would he? The cultural Christian thang is to be cordial to the ladies, but when you are looking at Jezebel, that has to be abandoned.
We are in a most uncomfortable position where shiny conservative credentials are looking like they have to take a back seat to effectiveness. Cruz seems like a very reasonable peacetime president. Trump has a mind for war on whatever, as he views it, keeps America from being great.
