State Sen. Doug Overbey, a Maryville lawyer, has pocketed a passel of endorsements in the 2nd District Republican primary. Newspapers, the National Federation of Independent Business and the Tennessee Education Association endorsed Overbey, along with Republican heavyweights Gov. Bill Haslam and, a bit surprisingly, Lt. Gov. Ron Ramsey, a tea party favorite. Given his opponent, Overbey needs all the help he can get. Scott Hughes, chief financial officer for a Knoxville church and former pro-life executive, is challenging Overbey at every turn, in every way. Though Overbey maintains an enormous financial advantage, Hughes has loquaciously roughed up Overbey in debates.
