A. If a voter’s mistake or omission in the completion of a document under this chapter does not prevent determining whether a covered voter is eligible to vote, the mistake or omission does not invalidate the document. Failure to satisfy a nonsubstantive requirement, such as using paper or envelopes of a specified size or weight, does not invalidate a document submitted under this chapter. In a federal write-in absentee ballot authorized by this chapter, if the intention of the voter is discernible under this state’s uniform definition of what constitutes a vote, an abbreviation, misspelling, or other minor variation in the form of the name of a candidate or a political party must be accepted as a valid vote.
