It’s super frustrating but as an example - my parents are deeply conservative and supportive of Trump, and also on the lower end of “wealth” and semi-retired. It is 100% misinformation. My Dad quotes the Fox news rhetoric like it’s facts, and regardless of me disproving most of the BS, he is completely brain washed. At this point Trump could run a live execution of his political opponents and the Trumpets would more or less shrug.
And if that is the only point worth voting for then so be it, but pretty sure there are vastly different stances on other things that should change your mind.
