I think this is the problem with a candidate who has never been a politician before. Most elected officials are in it for the long-haul and build up a pattern over time. They know how much to promise, how much to give into spectacle and how much people will hold them to their campaigning slogans if they get into office. Likewise the public knows how much they can trust them and how likely they are to actually stand by their statements when they have the power to do something about it.
Trump is saying whatever he likes and to supporters who are sick of political double-speech it sounds honest and great. If he were to get elected though, we have no idea whether he would actually turn these talking points into policy. Not that he even could since so many of the things he's stating are beyond the powers of the POTUS office, so he couldn't make them happen without a lot of political capital in the other branches of government. Some, such as the restriction of entrance to the United States on religious grounds, are blatantly anti-constitutional so he would have a hell of a time getting such things through the Supreme Court.
