CHICAGO (CBS) — A dozen polling places in Porter County, Indiana, will stay open later than normal, after problems that forced them to open late.

A Porter County judge signed an order keeping all 12 polling places open a full 12 hours. County election officials said the polling places opened late because some poll workers did not show up. Some precincts had only two poll workers at the start of the day.
