Takeaway quote:
"The researchers examined numerous variables that might have affected the vote outcome. These included the number of voters, their median income, racial and age makeup and the change in voter turnout between the 2000 and 2004 elections. Using this information, they examined election results for the Republican and Democratic presidential candidates in the state in 1996, 2000 and 2004 to see how support for those candidates and parties measured over eight years in Florida's 67 counties.
They discovered that in the 15 counties using touch-screen voting systems, the number of votes granted to Bush exceeded the number of votes Bush should have received -- given all of the other variables -- while the number of votes that Bush received in counties using other types of voting equipment lined up perfectly with what the variables would have predicted for those counties.
The total number of excessive votes ranged between 130,000 and 260,000, depending on what kind of problem caused the excess votes. The counties most affected by the anomaly were heavily Democratic.
Sociology professor Michael Hout, who chairs the university's graduate Sociology and Demography group, said the chance for such a discrepancy to occur was less than 1 in 1,000."
