This article has been revised to reflect the following correction:
The word ballot in the headline was updated to poll books.
There is now a back up plan in case electronic poll books go down again in South Dakota.
You may remember during the primary election, eight counties had trouble with their electronic poll books.
That caused delays in Pennington and Hughes Counties.
To make sure that doesn’t happen again, the secretary of state is recommending each county have a paper version of a poll book at each voter center in case the electronic poll books go down again.
