A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election.
In Mississippi, primaries are open, meaning any registered voter may vote in the primary of their choice. State law says: "No person shall vote or attempt to vote in the primary election of one (1) party when he or she has voted on the same date in the primary election of another party."[1]
