There were four special elections in 2011. Three were to fill Seats in the House of Representatives and one for a Senate Seat.
Here are the audit files and the Audit Reports for the 2010 General Election. The audit file links are to Zip files that contain the six audit files; EL30A, EL45A, EL68A, EL68, EL152 and EL155 that are extracted from the ES&S Election System (Unity) for the audits. The Audit Reprot links are to Adobe PDF files that can be read by the Adobe reader, available for most operating systems. If you need the Adobe Reader it can be obtained here. These reports were generated by the State Election Commission.
