How do primaries work in Illinois?
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. Illinois uses an open primary system. Voters do not have to register with a party, but they do have to choose, publicly, which party's ballot they will vote on at the primary election.[2][3][4][5]
For information about which offices are nominated via primary election, see this article.
How do I register to vote?
To register to vote in Illinois, a person must be a U.S. citizen, a resident of an Illinois precinct for at least 30 days prior to election day, and at least 18 years old by election day. A 17-year-old may vote in a primary if he or she will be 18 years old at the subsequent general election.[6]
Regular registration closes during the period beginning 27 days prior to an election and ending two days after the election. Online registration closes 16 days prior to an election. Grace period registration is available in person through election day at certain locations.[6]
Prospective voters can register online, by mail, or at any of the following locations:[7]
