Early Voting for the March 20 Presidential Primary Election is set to start Monday at five locations in Patch towns within south suburban Cook County.

Early voting also can be done at the clerk's downtown Chicago office, 69 West Washington St., and Cook County courthouses, according to Cook County Clerk David Orr, or any one of the 42 suburban sites listed on the clerk's website.

When: Feb. 27 through March 15. 

How: Early voters do not need a conflict or excuse to vote before election day, but they must have a government-issued photo ID such as a current driver's license, state ID, passport, or military ID. Voters must choose a party when casting a ballot in a primary election.
