Several counties throughout the U.S. experienced ballot shortages Tuesday, potentially leaving some Americans without a chance to cast their votes. Many counties point to unexpected high voter turnout.

Seven to eight polling sites in Wisconsin’s Racine County ran out of various ballots after 3 p.m. Tuesday after a heavy voter turnout, the Milwaukee Journal Sentinel reports. As Racine officials were scrambling to keep enough ballots at polling sites during the final hours, some went home without voting, and it's unknown how many stuck around or may have come back later. 

Several precincts in northern Indiana’s St. Joseph’s County, which includes South Bend, ran out of ballots Tuesday afternoon, WSBT-TV reports. Local Fox-19 reports that a local precinct inspector "estimates at least 10 people at his precinct left without voting."

In northern Kentucky’s Kenton County, several polling places experienced ballot shortages, according to Kenton County Clerk, Gabrielle Summe said voters would still be able to vote on “e-slate” machines, which do not use the paper ballots.
