Today is the deadline for Kentuckians and Illinoisans who need to register to vote in November’s presidential election. Mail-in registrations in Kentucky must be postmarked by today to be accepted. Voters who’ve moved since the last election should update their registration today as well. Those who have moved to a different county who don’t update their registration won’t be permitted to vote. To register in Illinois, voters must have lived in their precinct for at least 30 days before the election.
