On further reflection, Trump IS a good example as to whether people will VOTE for an arrogant candidate. But, the similarity breaks down in that Trump has not been elected - YET.  And of course, has not been re-elected. Then we have the Eugene problem.
In Eugene, we have 26% registered Republicans. Of the ballots cast, Republicans made up 28%. Trump got 66% of that. So if I am reading this right, he got 65% of 28%, or 18% of those registered voters.
All candidates were on the Mayor ticket. Of the total registered voters,  57% cast ballots. Vinis got 29% of all registered voters. I am not sure if I have these numbers correct but I have to leave. 

Because of our left leaning populace, people prefer the liberal "arrogance" to the conservative arrogance. But I don't think people will vote in an arrogant leader. At least, I hope.
