Ted Cruz is intelligent, too, but Trump should not trust him for anything. Paybacks are a b!tch, and he didn't go quietly into the night. Sean did give him due credit today for taking some hard stands that cost him personally.
But both are now high on my unlikeble meter plus Newt is a carryover from an unpopular administration. I wasn't paying too much attention in those years to the machinations in Washington, just Desert Storm, and see that he was forced to resign as Speaker of the House, then he resigned from the House altogether.
I hear you. My suggestion for Trump is use Newt in more of a background fashion. Maybe extensively but mostly on the QT.
