The sprawling 4th Congressional District will get a major facelift if a new political map released Friday gets approved by the Tennessee General Assembly.The 24-county district will be trimmed to 15 counties and include, most noticeably, Rutherford County.Under the proposal, the following counties would be dropped from the 4th District: Coffee, White, Cumberland, Hickman, Lewis, Lawrence, Giles, Fentress, Pickett, Morgan, Roane, Scott, Campbell, and a small portion of Williamson.Counties that would be added are Rutherford, Bedford, Marshall, Rhea and Bradley.Entering the redistricting process, state lawmakers identified the 4th District as one they wanted to change because it is currently one of the most rural congressional districts in the nation. Because of its sparse population, it forced one lawmaker to cover more than 25 percent of Tennessee’s 95 counties.“It’s not fair to the representative and it’s not fair to the constituents,” state Rep. Judd Matheny said during redistricting.Congressman Scott DesJarlais is serving his first term as 4th District representative and said Friday he hasn’t had time to fully evaluate the new district.“I haven’t had an opportunity to study these proposed new lines closely yet, but regardless of the new district boundaries I’m committed to continuing to be an independent conservative voice for Tennesseans,” DesJarlais said in a statement.DesJarlais could get a challenge from his own party as state Sen. Bill Ketron, a Republican from Murfreesboro, is considering a run. Ketron said he would make his decision in the coming weeks.State Sen. Eric Stewart, who currently serves Warren County, said he is excited about the reshaped 4th District.
