The punditry on CNN pre-poll coming out was moving to a sort of consensus that Trump won his base but not swing voters. He was playing to a Breitbart, Drudge, GOP primary audience and with them he did great. But maybe not so much with anyone else. And they keep coming back to the threat to jail Hillary as a 'gaffe'
It's not a gaffe. He was serious. We need to stop acting like what Trump says is just entertainment or for shock value. He listens to those he associates with, so no reason to think he wouldn't prosecute Clinton on recommendation from Bannon, Giuliani and Christie.
