The long Election Day lines around Florida may have turned away more than 200,000 frustrated would-be voters who gave up and went home before they cast ballots — or else saw the lines and elected not to join them.

Analyzing data compiled by the Orlando Sentinel, Ohio State University professor Theodore Allen estimated last week that at least 201,000 voters likely gave up in frustration on Nov. 6, based on research Allen has been doing on voter behavior.

His preliminary conclusion was based on the Sentinel's analysis of voter patterns and precinct-closing times in Florida's 25 largest counties, home to 86 percent of the state's 11.9 million registered voters.

"My gut is telling me that the real number [of voters] deterred is likely higher," Allen said. "You make people wait longer, they are less likely to vote."
