SOUTH MILWAUKEE, Wis. — A voting tabulator malfunction at a South Milwaukee polling location Tuesday morning temporarily disrupted ballot scanning, but voting continued using backup procedures, according to city officials. South Milwaukee City Clerk Steven A. Braatz Jr. said the tabulator at the District 4 polling site at the former Grobschmidt Senior Center went down shortly after polls opened. By late morning, voting operations had returned to normal. TMJ4Kristin, a South Milwaukee voter who cast her ballot later in the morning, said the process was smooth and quick once she arrived at the polling location. “There was no line here in South Milwaukee.”
