*Independent (IND) / No Party Affiliation (NPA) – these two categories are one in the same. When a voter writes Independent, I, Ind, no party affiliation, NPA, no party, no choice, none, non-partisan, line crossed off or the field is blank in the "Choice of Party" field on the voter registration form. (South Dakota does not have an Independent party)
**OTHER – This category is for voters who write any other political party on their voter registration form that is not currently a recognized political party in South Dakota.

NOTE: The South Dakota Democratic Party has opened their primary election up for all voters registered as independent/no party affiliation to vote in their primary. Voters registered in the “other” category are not allowed to vote in the SD Democratic Party primary.
