## Highlights

In November 2006, about 18,000 undervotes were reported in Sarasota County in the race for Florida's 13th Congressional District (FL-13). After the contesting of the election results in the House of Representatives, the task force unanimously voted to seek GAO's assistance in determining whether the voting systems contributed to the large undervote in Sarasota County. GAO agreed with the task force on an engagement plan, including the following review objectives: (1) What voting systems were used in Sarasota County and what processes governed their use? (2) What was the scope of the undervote in Sarasota County in the general election? (3) What tests were conducted on the voting systems in Sarasota County prior to the general election and what were the results of those tests? (4) Considering the voting systems tests conducted after the general election, are additional tests needed to determine whether the voting systems contributed to the undervote? To conduct its work, GAO met with officials from the State of Florida, Sarasota County, and Election Systems and Software (ES&S)--the voting systems manufacturer--and reviewed voting systems test documentation. GAO analyzed election data to characterize the undervote. On the basis of its assessments of prior testing and other activities, GAO identified potential additional tests for the Sarasota County voting systems.
