I’ve been seeing a lot of anti-voting sentiment going around. Can’t believe I have to say this, but you need to vote. Not only is there more to the election than just the president. (State policy, Senate, house), but not voting is not an act of protest. C’mon guys
The first instance is realistically the only case in which it would really matter that you spoiled your ballot, though. In the second example of when you might spoil your vote, it wouldn’t really matter at all, precisely because they have a large enough majority.
