I witnessed the same type of thing happen in the Santorum-Casey race in Westmoreland County, PA. Straight R vote cast a vote for Casey. That is no “calibration” error.
IIRC that was the day that 800 machines in the county wouldn’t open on Election Day because they had already been voted on. Apparently there is a safeguard built in that is intended to prevent you from inputting votes other than on Election Day. I called the Santorum campaign, the county Republican HQ and the county elections office (run by D’s then). Nobody did a damn thing.
The county later blamed the machine vendor for a programming error. Riiiight.
Funny how those “programming errors” never switch from the Democrat to the Republican.
Sounds like the ‘voting’ in my precict. I inserted the ‘credit card’ thingie and the machine announced ‘this vote has been cancelled’.
And then there’s this:
