https://en.wikipedia.org/wiki/List_of_political_parties_in_Minnesota#Recognition
Qualifying as a recognized major or minor political party is determined by how many candidates a party nominates for certain partisan offices, how well candidates for statewide office do in certain partisan elections, or a petition that has the required number of signatures. Generally, a party that presents a statewide candidate that receives at least five percent of the vote or presents a petition to the secretary of state containing a number of signatures equal to at least five percent of the number of individuals who voted in the preceding general election qualifies as a recognized major party. Similarly, the threshold is one percent to qualify as a recognized minor party.
Parties recognized as a major or minor party are eligible to receive funds from the state elections campaign account. Recognized major parties also have automatic ballot access.[2]
Thanks for the info.
