Nashville Senate Candidates Talk About Per Diem, Other Issues

The two candidates for Senate District 20 -- Republican Steve Dickerson, a doctor, and Democrat Phillip North, a lawyer -- both say they would refuse per diem money if elected, but each has a different idea about what to do with it. The Tennessean interviewed them both about this and many other subjects in their quest to fill the seat of Sen. Joe Haynes, who is retiring after 28 years.
