Some Christian friends tell me they can’t in good conscience vote for Donald Trump because, when faced with a choice between "the lesser of two evils," the morally right thing is to choose neither one. They recommend voting for a third-party or write-in candidate.
As a professor who has taught Christian ethics for 39 years, I think their analysis is incorrect, for reasons that I will briefly mention here and that I have explained in greater detail elsewhere:
I did not support Trump in the primary season, but now that Trump has won the GOP nomination, I think voting for Trump is a morally good choice because he will do more good for the nation than his opponent. I do not think Trump is an "evil candidate," but rather a good candidate with flaws.
If this election is close (which seems likely), then if someone votes for a write-in candidate instead of voting for Trump, this action will directly help Hillary Clinton, because she will need one less vote to win. Therefore the question that Christians should ask is this: Can I in good conscience act in a way that helps a liberal like Hillary Clinton win the presidency?
Clinton would quickly replace Justice Scalia with another liberal like Breyer, Ginsburg, Sotomayor, and Kagan. This would give liberals a 5-4 majority on the Supreme Court even without Justice Kennedy, and 6-3 when he votes with them.
But that is not all.
