DOES INDIANA REGISTER PARTY AFFILIATIONS?
Indiana law does not permit a person to indicate their party affiliation, if any, as part of their registration record.
Indiana has open primaries. Any registered voter can participate in primary elections, regardless of political party. If you are affiliated with either the Democratic Party or the Republican Party, you are entitled to vote for candidates of that party at the primary election. However, you must state which party you are affiliated with by asking the poll workers for the ballot of that party. You may only vote for candidates in the party whose ballot you select.
