I don't think this kind of exercise is that difficult, and I get plenty of practice on HN talking to people who have very right-wing ideas about the economy. But come on; it's not a way of working miracles. You might persuade your uncle who loves Donald Trump to moderate a couple of positions; you aren't going to turn him away from the Republican Party.
This is the main reason that election campaigns have moved on and focus much more heavily on turning out their own supporters than persuading "undecided" voters, who are a statistical nullity.

Actually it is surprisingly likely..IF you're willing to do the hard work of moral reframing to put it from their views and values. See https://www.nytimes.com/2015/11/15/opinion/sunday/the-key-to... for more about that.
That said, few people of any political persuasion are able to engage in that exercise.
