We might have President Hillary or Cruz if it wasn’t for Bannon. Yes he made mistakes on Moore though. Moore wasn’t a fast enough thinker on his feet and communicator for the level of attack he came under. Look at how hard the Democrats worked to get their man Jones and how much the Republicans did everything they could to find a way to lose. Ben Shapiro even was talking on air about how Republicans shouldn’t be voting for Moore.
Bannon has never hesitate to take the credit for Trump’s victory. If he can take that credit, then he can take this criticism for pushing such a poor candidate.
