There are not that many cultural universals, that is ideals or behaviors shared by people worldwide. One of those universals is that humans generally dislike change. We all have things which give us great comfort; our homes, our jobs, our families, our friends. When these things are threatened we become very uncomfortable.
In America we have a political system which threatens big changes every four years. As the the time draws near to election day we become more and more uncomfortable.We lash out at others, name call and take hardened positions as to which candidate will change our nation in a way we would be most comfortable with. But in truth we don't really want much of anything to change so we seek a leader who will keep things the same as they are.
Ironically  new citizens, refugees and immigrants  introduce us to change regardless of election cycles. The same is true for the climate. We may not like it but sometimes we must adapt to things out of our control. That's life.
