Election officials in Cambria County filed an emergency petition to extend voting hours after voters were left unable to scan their completed ballots on Tuesday.

The most common disruptions at precincts are late openings, lack of staffing and voting machine issues, according to Jeff Greenburg, a 13-year election director veteran. He is now a senior advisor on election administration for The Committee of Seventy, a nonpartisan organization focusing on engagement and public policy advocacy.
