Bradley County Sheriff Tim Gobble (R) threw his hat into the ring on Thursday for the seat that Rep. Zach Wamp (R) is vacating to run for governor.

“As your congressman, I will work with you in a partnership of progress to blend the finest traditions of our past with fresh ideas and innovation for our future,” said Gobble, a former city council member and former U.S. Secret Service agent.

The conservative who was elected sheriff in 2006 is the first Republican in the race, but the field is expected to get crowded.

Other potential GOP contenders who are garnering attention in Republican circles are state GOP Chairwoman Robin Smith, state Sens. Bo Watson and Dewayne Bunch and businessman Wayne Cropp. Smith said she plans to make a decision on the race by March.

Democrats are not expected to contest the staunchly conservative 3rd district seat.
