Your friend loves your least favourite politician. What do you say?

This question's on my mind because my coworker today mentioned they would vote for Trump if they could (mind you this is 2023, in Canada). I don't generally have the talking points or the desire to fight about it, so I just deflected the conversation. But I often wish I was more strong-willed and could try to figure out why someone believes what they do and, if it's invalid, then convince them otherwise.

Thus, I'm curious what you all would say or what you've done in the past!
