Tennesseans going to the polls on the last day of early voting were adding to what has already been a record turnout among state voters. Turnout through Wednesday was 1.38 million — about a quarter-million more voters than the previous early voting record set in the 2004 presidential election. State Election Coordinator Brook Thompson expects that about 1.5 million people will have cast ballots in the election. Election Day is Tuesday. Thompson projects that overall turnout will easily exceed the 2.45 million who voted in 2004. There are nearly 4 million registered voters in Tennessee this year, including more than 360,000 who have registered for the first time this year. No major problems at the polls have been reported so far. Shelby County has seen the highest turnout in the state with nearly 227,000 early voters so far, followed by Davidson County with 172,000 voters.
