Sarcasm, a joke or idiocy?

Take your pick? Donald has said things that were insulting, were lies and blatantly false rhetoric. Every time he says something, he says it was a joke or it was sarcasm. Now, since the Media has finally figured out that Trump is a fraud, he is walking back everything he says! I had to laugh when they say that he isloosing his mind! We knew this over a year ago, like since the birther issue. He isn't loosing his mind, it call be an egotistical person who needs attention and thinks is better than and knows more than others. He can't stand being behind! So, a question for all those who say they support him, still won't distance themselves from Trump and put an end to this pathetic run for president?
