“We have received numerous reports of “vote switching,” most through members of the media or on social media. In each case where we have received reports from a voting district, we are sending leads out to those polling places to verify that the machines are working correctly. In each of those cases, there has been no evidence that the machines are working incorrectly. This includes reports in Robinson, West Deer, Hampton and Sewickley Hills.

“In every election, there are machines that need to be recalibrated following transport. So far today, we have reset three machines - one each in Upper St. Clair, Monroeville and West Mifflin. This is in line with what we see each election.”
