Is Donald Trump ever going to go 'too far'?

The only explanation I can come up with is that he entered the race as a lark and never expected to get anywhere. As he started polling well, he started to come up with crazy positions that would allow him to exit by saying "I was right, but nobody listened." Because he has rejected PAC money, a full fledged run would bankrupt him. As he gets more support, he gets crazier just to avoid having to run. I suspect a future move will be to endorse Clinton hoping that he would loose all his support.
