Yesterday, we reported about a tweet sent by Governor-elect Greg Abbott about faulty voting machines in Bexar County. Abbott remarked on a tweet originally sent by Bexar County voter Jade Stanford, who claimed that her ballot screen incorrectly displayed David Dewhurst's name as the Republican candidate for governor instead.

Bexar County Election officials never returned our calls for comment, but Elections Administrator Jacque Callanen told the San Antonio Express-News she believed the photos published on Twitter were doctored.

That seems plausible, but it turns out that wasn't the case. Today, the Express-News reports that Election Systems & Software, the makers of the iVotronic ballot machines used in Bexar County, has acknowledged that there was indeed a ballot glitch that lead to the display of Dewhurst's name. The company blames the error on a faulty memory card.

Their full statement is below.

On November 4, 2014, an issue was reported with a single voting unit in a Bexar County precinct in the General Election. An initial analysis by Bexar County and the ES&S technician on site has confirmed that the unit in question was not functioning properly and was incorrectly displaying a candidate in one race on the touch screen. The unit in question was immediately removed from use and no further issues were reported. There were a total of 12 votes cast on the unit and all votes were tabulated correctly. The results tape did reflect the correct candidates for that race and no votes for compromised. While it currently appears that a faulty memory card is at issue, a full review and diagnostic test is underway to determine and validate the exact cause of this issue. Once this review is complete, ES&S will provide a report to Bexar County detailing the outcome of the forensic analysis. Bexar County followed proper protocol and procedure in all testing, coding and equipment preparation.
