Indiana’s primary election day is a state holiday on which state government is closed, including the Secretary of State’s office. A primary election is a preliminary election in which voters nominate party candidates for office. Voters select candidates for subsequent elections. It is one way that a political party nominates candidates for an upcoming general election. Primary elections are common in the United States and are conducted by the government on behalf of the parties. Indiana primaries are “closed” primaries. When voters sign in at their polling place, the clerks ask them which political party’s ballot they prefer. They vote for only the candidates on that ballot. In the primary, voters nominate the candidates of their party who will be on the ballot in the general election. In Indiana, polling places are open from 6 a.m. to 6 p.m. local time.
