In my opinion, he doesn't really even have any policies. He refuses to go into detail on any of his given "policies", and simply responds with comments like "I know more about this topic than anyone". His broad brush approach claims he will fix everything, including terrorism. This in itself isn't much different from other politicians, but he intentionally does not go into any details on how he will accomplish anything.
I think Trump will end up winning because he isn't playing the same political game Hillary or anyone else is playing. He is purely using psychological tactics to gain voters. Playing on their fears or anger and intentionally giving other candidates nick names like "Lying Ted", or "Crooked Hillary". These tactics may seem silly or childish to most intelligent people, but once you hear a nickname, and the person does any activity that reminds you of their nickname it does affect how you view them, even if only at a subconscious level.
