For the record, this does not include hypothetical write-in votes for Lucifer or emoticons, as a "statement" is defined as a grammatical unit containing both a subject and a verb. It would also have left valid the traditional write-in favorite, "All of these candidates are great/are terrible," as such applies to the entire slate, as opposed to a particular candidate.
