Problems in key US presidential election
Voters in the swing state of Pennsylvania are having a hard time at some polling stations in the US presidential election, CNN reported.
In Pennsylvania, ballot scanners were reportedly apparently broken and they promised to "scan again later."
Cambria County extended voting hours after a software glitch made it difficult for voters to scan their ballots.
Pennsylvania is a key swing state and could decide the outcome of the election. On the eve of the presidential election, the Pennsylvania candidates were almost tied.
