I think it's fair to maintain Trump is unfit for office due to his past actions. This man would be responsible for sending people into war, asking them to lay down their lives and their relatives to suffer this loss. He is way too reactionary, impetuous and petulant to be entrusted with this incredibly important responsibility.

Trump does't care for people, is cruel and vindictive towards them when they disagree with him and above all is a demagogue; I doubt he really cares what anyone thinks as long as they vote for him.

He is utterly bereft of any personal or professional integrity.
