"On our call with USPS and @illinoissbe, USPS said that IL voters planning to vote by mail should request a mail-in ballot no later than Oct 19 and return their ballots no later than Oct 27. Illinoisans must be able to vote safely w/ confidence that their ballots will be counted."
"Illinois also has a law that any ballot postmarked on or before Election Day will be counted if received by the election authority within 14 days after the election."
