Election officials say nearly a quarter of Illinois counties and the city of Aurora are reporting that some primary ballots are too large and don't fit into scanning machines.
Rupert Borgsmiller of the Illinois State Board of Elections says all votes will be counted, but tallying may go slower than usual in affected counties.
He says ballots from two vendors are causing problems in 25 counties. But not all precincts in those counties are affected. Some ballots are fine, even in the affected precincts.
Counties reporting ballot size problems are: Winnebago, Vermilion, Iroquois, Douglas, Knox, Grundy, McLean, Warren, Lee, Bond, Bureau, Christian, Clark, Coles, DeWitt, DuPage, Edgar, Macon, Macoupin, McDonough, Moultrie, Putnam, Rock Island, Shelby and Tazewell.
