Some voters report problems at the polls

Some voters said they were given provisional ballots at the polls.

Channel 2’s Audrey Washington

talked to voters in Cobb County who said there were problems with the machines at Blackwell Elementary School.

The Cobb County elections director told Washington that the “check-in express” polling units did not have power Tuesday morning because the batteries were drained. So while things were getting fixed, for about 45 minutes, seven provisional ballots were handed out.

One voter said she wished the voting location would have been better prepared.

“I think that they handled themselves professionally, the ones that were sitting at the desk. The others were walking around wringing their hands. There was nothing that they could do, and they didn’t know what to do,” said Veronica Lilly.

Some of the voters with provisional ballots questioned whether their vote would actually be counted.

The director of elections said because there is no question about eligibility, every vote will be counted.
