Think of all the people that Donald J. Trump has offended so far.
What are the traits of a good leader or a politician? Think of Abraham Lincoln, think of Nelson Mandela, think of Martin Luther King, think of the founder of Pakistan, Mohammad Ali Jinnah, think of Jesus. Now, think of Donald J. Trump, and his big mouth, and the way it moves when he boasts about how rich he is, and then insults everyone he feels is not important to him or his victory.
I'm sure you must have or have had a grumpy, ill-mannered, bullying kind of a person, somewhere in your neighborhood, who just assumes you are going to be in his way making his life more difficult. That is him. That is Donald J. Trump. He is your nasty neighbor.
