I absolutely hate discussing politics. I always tell my parents the actual person I am voting for. However, I loathe being asked by strangers/acquaintances who I am voting for.
If an acquaintance walks up to me and asks me who I am voting for (classmate/parishioner/etc.) I always tell them I’m voting for Mickey, Mickey Mouse. I don’t tell them that I’ll be voting for Donald Trump because they might get angry/offended and start an argument. I don’t want to make any enemies. I just want to get along with people.
So here’s the thing: Lying is bad. That I know. But this is a case which is pretty unusual. This is clearly not grave matter in the least (at least I think.) Thus it wouldn’t be a sin. The question, however, remains: When is lying a sin?
