Politics is just applied ethics.
Why on earth would I stay friends with someone whose applied ethics put them in league with Donald Trump?
Because they didn't put much thought into applying their ethics, like the vast majority of voters (who lack a consistent philosophy). Even if one had no good reason for voting for a bad candidate, it's wise to keep in mind that most people vote for any and all candidates weren't giving much thought to their reasoning before wielding what amounted to a very small influence in a large democracy.
