Cuyahoga County, OH notices higher voter error rate as VBM increases

A story in The Plain Dealer notes that voting errors increase as the use of vote by mail increases. 

What’s interesting about this story is that it focuses on a basic mechanical “mistake,” meaning that voters failed to include a proper form of identification or did not use the secrecy envelope.  The much more common error results from voters mis-marking the ballot (over and undervotes).  Residual vote studies have long shown higher rates of voter errors whenever a central count system is used, where voters are not given real-time feedback on the accuracy of their use of the ballot.
