The University of Connecticut Voting Technology Research (VoTeR) Center received the data gathered in the post-election audit performed in the State of Connecticut following the November 2007 election. The audits of the randomly selected 10% of the districts were conducted in November and December of 2007, and the returns were conveyed by the Office of the Secretary of the State to the VoTeR Center on January 8, 2008. The audit data received by the Center contains 958 records, where each record represents information about a specific candidate. Specifically, each record contains the following significant information: date, district, machine seal number, office, candidate, machine counted total, undisputed hand counted total, questionable hand counted total, overall hand counted total, that is, the sum of undisputed and questionable ballots. This report contains several statistical analyses of the audit returns and recommendations. Among the 958 records received by the Center, 175 records (18.3%) were incomplete, unusable, or obviously incorrect. Another 111 records (11.6%) contained usable, but incomplete data, or minor arithmetic errors. Thus about 70% of the audit records were complete and contained no obvious errors. While some problematic records were clearly due to human error (e.g., in addition), this suggests that auditors found the audit instructions to be ambiguous or insufficiently specific.

The UConn VoTeR Center performed a partial post-election audit of the memory cards for the AccuVote Optical Scan tabulators that were to be used in the November 2007 Connecticut Elections. The cards were programmed by LHS Associates of Methuen, Massachusetts, and shipped to the towns in Connecticut. The research and development required to perform the audit and the methodology and procedures used to conduct the audit are essentially identical to what was used to perform the pre-election memory card audit, and we refer the reader to our earlier report to avoid a complete restatement.

The UConn VoTeR Center performed an audit of the pre-election memory cards for the AccuVote Optical Scan tabulators that were to be used in the November 2007 Connecticut Elections. The cards were programmed by LHS Associates of Methuen, Massachusetts, and shipped to the towns in Connecticut. The towns were instructed to test the cards and to choose randomly one out of each four cards per district to be shipped for the audit.
The total of 522 cards were received and tested by the VoTeR Center, out of which 378 cards were received before the election. Out of the total number of cards, 18 cards, or 3.5% were found to contain “junk” data, that is, they were unreadable, which is easily detected by the tabulators as such, and could not have been used in the election. The rest of the cards, or 96.6%, were found to have been properly programmed for election. These cards contained valid ballot data and the executable code on these cards was the expected code, with no extraneous data or code on the cards.
