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. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. In Illinois, state law provides for a closed primary where a voter must be affiliated with a party to vote in that party's primary. However, voters state their affiliation at the polls and any voter may change their affiliation on the day of the primary. A voter's eligibility to vote a party's ballot may be challenged.[1]
