This is pretty much what I say when I know somebody who professes to be a Christian, or whom I think might believe he or she is a Christian, if they ask me about my politics. I just say "Well, I'm a Christian, and the Bible says we should help the poor, welcome the foreigner, heal the sick, respect others, not commit adultery, not lie, and not steal, so of course, as a Christian, I can't support Trump." It just totally disarms them. When Biden was President, I'd say "outwardly, Biden is a much more Christian man. He treats others with respect, wants to help the poor, welcomes foreigners etc .. but I can't support his policies." I tell them I can't support Biden's policies because I want to disarm them. The first thing you have to do is drive a wedge between them and Trump. So I then add "so what's a guy to do? I can't support one of them because he's immoral and doesn't live in a Christian way and the other I can't support many of his policies." Then I change the subject. You're not going to make somebody change his opinion about who he supports in one fell swoop, overnight. You have to slowly break them down. I just watched my new brother-in-law, who supported Biden, do this with my sister, who was a Trump supporter.
