The most prominent example is "Super Tuesday," usually in March, where as many as a dozen states hold either primary elections or caucuses.
Most primary elections fall into one of two categories: closed and open. In a closed primary, only members of a particular party can vote in that party's primary. In contrast, an open primary is open to all voters. Most New York primaries are closed primaries.
