Maybe it was because Mayor Bill Haslam's campaign never seemed seriously threatened by Democrat Mike McWherter. Maybe it was because after six months of primary and general elections, local voters were just a little tired. Whatever the reason, Knox County turnout was lower Tuesday than in either of the last two gubernatorial elections. Unofficial results put the total county vote at about 106,000, about 20,000 fewer than in 2006 and 10,000 fewer than 2002. There are about 279,000 registered voters in Knox County, which makes Tuesday's turnout about 38 percent. The good news for Haslam, of course, is that he got 81 percent of those votes—which means that about 30 percent of Knox County registered voters turned out for him.
