The way Trump makes deals and proposes plans is a lot like a salesman. At first you set the bar as high as possible, higher than you actually expect to come to terms. Then even after negotiating/haggling, he gets a better deal than if he were to have gone in with a more reasonable proposition. Inevitably just about anything that Trump has promised at face value becomes a gross exaggeration of what he probably expects to negotiate. I guess this could be seen as deceptive, but it is honestly a good thing that he shows a willingness to negotiate. I have seen him soften his stance on a good handful of issues, but I dont think he has flip-flopped entirely on any of them to this point.
