this doesn't exactly inspire confidence in the system
Government Accountability Office
In 2014, the Government Accountability Office, which describes itself as "an independent, nonpartisan agency that works for Congress," conducted a literature review of studies into in-person voter fraud.[6] The review stated the following: "Five states provided us with investigative studies that focused on specific types of election fraud. ... The one study that included some information on allegations of in-person voter fraud examined instances of votes cast in the name of deceased persons in one state. It examined about 200 questioned votes that were cast in the November 2010 election and ultimately determined that all but 5 of the questioned votes could be attributed to errors by state or local officials—including clerical errors, data matching errors, errors in scanning voter registration forms, and the issuance of absentee ballots in the wrong name—or to applications for absentee ballots by voters who died before the election. For the remaining 5 allegations, the study could not conclusively determine whether in-person voter fraud occurred."[7][8]
