This is key: The original meaning of religion is "a binding relationship," so for many (Right and Left), their ideology becomes their religion (or idol) because it literally is that "binding relationship" impacting their worldview.

The real test? Who or what is at the top of your priority list? Meaning, what do you hold sacred? For many, politics is their religion and their presidential candidate becomes their "god," and the leader of the other side (Trump, Obama, etc) becomes their devil.
