My least favorite thing about election culture in the US is when individual people say things like "Make sure to vote!" and don't actually say how they think you should vote. It means one of a few things:

1) they think it's rude to discuss specific policy or candidates
2) they think their position is the "true" majority and if everyone voted it would all be ok
3) they actually don't care how you vote

1 & 3 are morally awful, 2 just seems like hubris
