Three Putnam County voters say electronic voting machines changed their votes from Democrats to Republicans when they cast early ballots last week.
This is the second West Virginia county where voters have reported this problem. Last week, three voters in Jackson County told The Charleston Gazette their electronic vote for "Barack Obama" kept flipping to "John McCain".
In both counties, Republicans are responsible for overseeing elections. Both county clerks said the problem is isolated.
They also blamed voters for not being more careful.
"People make mistakes more than machines," said Jackson County Clerk Jeff Waybright.
Shelba Ketchum, a 69-year-old nurse retired from Thomas Memorial Hospital, described what happened Friday at the Putnam County Courthouse in Winfield.
"I pushed buttons and they all came up Republican," she said. "I hit Obama and it switched to McCain. I am really concerned about that. If McCain wins, there was something wrong with the machines.
"I asked them for a printout of my votes," Ketchum said. "But they said it was in the machine and I could not get it. I did not feel right when I left the courthouse. My son felt the same way.
"I heard from some other people they also had trouble. But no one in there knew how to fix it," said Ketchum, who is not related to Menis Ketchum, a Democratic Supreme Court candidate.
Ketchum's son, Chris, said he had the same problem. And Bobbi Oates of Scott Depot said her vote for incumbent Democratic Sen. John D. Rockefeller was switched to GOP opponent Jay Wolfe.
"I touched the one I wanted, Rockefeller, and the machine put a checkmark on the Republican instead," Oates said of her experience Thursday.
She said she caught the mistake, called over a worker in the county clerk's office and was able to correct her vote. But she worries other voters may not catch such a mistake.
When asked if she is sure she touched the box for Rockefeller, she said, "I'm absolutely positive."
Putnam County Clerk Brian Wood said on Saturday that he is upset there are "so many negative stories out there and not enough positive ones. We want people to vote. People need to know the facts.
