Hi dC,
I would agree with that.  I think it also boils down to 'what' we expect from someone in the performance of their job.  Everyone has a nature.  We each individually have ways that we think and ways that we communicate and respond to others.
Some believe that everyone's out to get them and some are more understanding of others and try to see things from the way that others see things.  Going back to a driving analogy...we read of cases of road rage.  Some driver cuts another driver off.  Some go out for blood and spend the next 15 minutes trying their best to show their anger at how they've been treated.  Some are more calm about it and back off and allow the other driver some space.  It really boils down to grace or revenge.  We all have ways that we react and respond to stimulus.  These attitudes become ingrained and a part of the nature of 'who' we are.
 The one who gets angered likely gets angered with others who make mistakes in other things.  The one who gives grace likely gives grace in other things.  It's a nature and we all have one.  Now, we can also replace the word nature with spirit.  Some people have a mean and wicked spirit.  Some have an understanding and forgiving spirit.
Unlike you, when I see the nature of the man, Donald Trump, I'm not willing to give my approval for his being the leader of the nation.  I don't want to be known or associated with someone with such a mean spirited nature.  Just as if I knew someone who was angered at everyone's mistakes or driving habits on the road, I wouldn't choose to ride in a car with them.  Paul writes for us an entire litany of sinful habits that are going to permeate society as we move inexorably toward the last days.  He ends that long laundry list with this warning:  Not only do they do such things themselves, but they approve of others who do them.
I'm not willing to give my approval to someone who seems to be practicing many of those sinful habits that Paul writes to us about.  I'm not willing to give my approval of someone who's love for most seems to have grown cold.  Someone who seems to be pretty loose with the truth.  Someone who denigrates and demeans others and spends the majority of his efforts seeing to it that his ego is fed.  For me, that's just not the better choice of a national leader or good friend.  No matter their political agenda.  I'm looking at the nature first and then the political promises or hoped for achievements.
Hopefully, this helps to explain my reluctance and refusal to cast my ballot for Donald Trump.  Donald Trump is unique in that such things as one's nature hasn't really been a big deal in national politics.  Most previous seekers and winners of presidential elections, in the past of my memory, were fairly decent people in how they worked with and communicated to others.  Now that's all been turned up on it's ear.
God bless,
In Christ, ted
