Cobb is the only candidate in the Democratic primary, which came about after his brother Curt resigned his seat in June in order to accept the position of Bedford County Clerk and Master, the court clerk for Chancery Court.
Four candidates -- Joseph Byrd of Unionville, Pat Marsh of Shelbyville, Bobby Scott of Shelbyville and Casey Walters of Fayetteville -- are running in the Republican primary. Chris Brown of Shelbyville has qualified for the general election as an independent.
"I pledge to work with every member of our community in order to meet the challenges we face head on," said Cobb in a statement released Friday. "I have been especially encouraged by the strong response to my campaign from Democrats, Republicans and Independents."
Described as a conservative Democrat, Cobb was born and raised in Bedford County where he attended Shelbyville Central High School. He also attended Martin Methodist College where he was a pitcher on the college's baseball team.
Cobb is a farmer in Shelbyville and has also worked for 22 years as a UPS delivery driver. The announcement said that Cobb has "deep family roots in both Lincoln and Bedford Counties."
"Growing up, my family taught me the value of hard work and public service," Cobb said. "I am announcing today that I want to take those values and represent the people of the 62nd District.
"I have been going door-to-door for over 20 years, I know where the rubber meets the road and I am not afraid of heavy lifting. We need someone with energy and a strong work ethic to represent us in these tough economic times, and I understand fully what working men and women are going through," Cobb stated.
"My family, my children and my community are the reasons why I am running."
The announcement describes Cobb as a "commonsense conservative," as well as "a hunter, fisherman, trail rider, sportsman, and a carry permit holder. He is pro-life and a card carrying member of the NRA.
"He also belongs to Ducks Unlimited, the National Wildlife Turkey Federation, the Shelbyville-Bedford County Chamber of Commerce, and the Fayetteville-Lincoln County Chamber of Commerce," the announcement stated.
Cobb has a daughter, Jordon, and a son, Trevor.
