GRAND RAPIDS, Mich. (WOOD) — More than 12,000 Kent County voters cast their ballots on Saturday, the first day of early voting for the upcoming general election. But it wasn’t without some issues.

According to the Kent County Clerk’s Office, a paper jam at an early voting site in Grand Rapids required service and forced some voters to insert their ballots into a secure auxiliary bin instead of the tabulator.

“This is not out of the ordinary, and we never want these minor issues to delay the voting process and inconvenience voters,” Kent County Clerk Lisa Posthumus Lyons said in a statement. “So, our tabulators are equipped with these bins to allow them to continue casting their ballots in a secure manner.”

According to Posthumus Lyons, only election workers have access to the auxiliary bins. Once the tabulator is fixed, those ballots are collected and fed into the machine by two election workers, one Republican and one Democrat.

Nearly 152,000 absentee ballots have been issued across Kent County, and 64% of them have already been returned. According to the clerk’s office, with those absentee ballots combined with today’s early vote, Kent County is already at 20% voter turnout.
