Since I haven't hung out with the guy, I can't say for sure. But from the little I know, he seems about as authentic as any politician can be. If he were concerned with attracting votes and actually becoming president, he would not openly express ideas that are considered radical by most people at both ends of the political spectrum. Liberals don't want all forms of welfare abolished, and conservatives generally want to keep drugs illegal and are against an extreme, isolationist policy. So at the least, he seems to say what he actually thinks, whether people are going to like it or not.
