My Republican Friend

I have an old friend who describes himself as a life-long Republican. He is critical of Biden and seems even more critical of Trump. He says he hasn’t decided whom to vote for. I know him to be a person who is highly intelligent and has high moral character. I should be able to communicate with him about the election, but feel at a loss as to how to begin. It’s as if he said he was undecided as to whether pigs can fly. How do you begin to explain that they can’t? I’d like to begin by telling him that if Elizabeth Warren’s golden retriever, Bailey, instead of Joe Biden, were running against Trump, I would vote for Bailey, but I know that saying that wouldn’t fly any better than a pig.
