Minn. Stat. § 204B.38: NAMES ON BALLOTS; IDENTICAL DESCRIPTIVE WORDS.

When the similarity of both the first and last names of two or more candidates for the same office at the same election may cause confusion to voters, up to three additional words may be printed on the ballot after each surname to indicate the candidate's occupation, office, residence or any combination of them if the candidate furnishes the identifying words to the filing officer by the last day for withdrawal of candidacy.
