Four Illinois counties extended their polling hours for the Democratic and Republican primaries. Effingham, Sangamon, Adams and McHenry counties all kept their polls open until 8:30 p.m. during the Tuesday primary.
Officials in Effingham, Adams and Sangamon counties say the delay was caused by an unexpectedly large turnout of voters on both the Republican and Democratic side. Officials in all three counties were printing ballots 'constantly' to meet the demand.
McHenry County kept it's ballots open due to an error in some voting machines early Tuesday morning. Officials say the error did not cause any problems with voters.
