Trump supporters -- why do you support him?

Question says it all, really. With the American election drawing closer and closer, the support Trump has been getting has gone beyond a joke for me. I'm actually genuinely curious. Trump supporters, can you explain to me just what it is about Trump that makes you believe he can't be stumped?
