In-person early voting at two locations in Chicago begins Thursday and in addition to selecting their pick for mayor and local aldermen, voters will be asked to choose three members of the 22 newly created police district councils based on the police district in which they live. 

But with four of the 22 police district councils having less than three official candidates listed on the ballot for the three open seats in each district, at least three write-in candidates are all but guaranteed to win elected office — a rarity in Chicago. The civilian oversight body and the mayor will be tasked with appointing at least one candidate to fill an open seat on one of the district councils.
