After working a 10-hour shift on Election Day, painter Richard Jordan headed to his east Orange County polling place at about 4:30 p.m. Based on more than a decade of voting, he expected to be in and out in minutes. Three hours later, Jordan's back ached, he was hungry, thirsty - and nowhere near a voting booth. So he left. As it turned out, his Goldenrod Road precinct didn't close until 11 p.m. Like Jordan, as many as 49,000 people across Central Florida were discouraged from voting because of long lines on Election Day, according to a researcher at Ohio State University who analyzed election data compiled by the Orlando Sentinel. About 30,000 of those discouraged voters - most of them in Orange and Osceola counties - likely would have backed Democratic President Barack Obama, according to Theodore Allen, an associate professor of industrial engineering at OSU. Allen's first analysis of the impact of long lines at the polls was done in 2004, when he estimated that more than 20,000 voters in Franklin County, Ohio, where Ohio State is located, were discouraged from casting ballots in the razor-close contest between President George W. Bush and Democrat John Kerry. His review indicated that for every additional hour that a precinct stayed open past 7 p.m. - a good indicator of line length throughout the day - turnout dropped by as much as 4.8 percent. The precincts with the longest lines, he found, had some of the lowest turnouts.
