What Tennessee Republicans are calling a unity tour is scheduled to be in Cookeville Thursday -- but not with everyone on board. State Senator Diane Black won the nomination for Congress in the 6th District, just 300 votes in front of Lou Ann Zelenik. State Senator Jim Tracy was a close third. The state party announced a unity tour Wednesday with stops in Hendersonville, Cookeville and Murfreesboro. Zelenik, who did not concede the race for two weeks, is not scheduled to appear with her former opponents. A press release from the party says that Black will be joined by Jim Tracy, Kerry Roberts, and Gary Mann in Cookeville- the second stop on a Sixth District General Election kickoff tour that includes stops in Sumner, Putnam, and Rutherford Counties. Tennessee Republican Party Chairman Chris Devaney will also be joining candidates on the tour as they discuss the importance of electing a Republican to the conservative district that has been in the hands of Democrats for more than two decades. The stop in Cookeville is scheduled for 12:30 at Republican party headquarters on Broad Street.
