At least two people have announced their intentions to challenge 25th District state Senator Jim Summerville of Dickson in the 2014 Republican primary. On Monday, former state Sen. Kerry Roberts of Springfield announced his plan to run, joining Wayne White of Slayden as confirmed candidates. The Robertson County Times also reports that 66th District state Rep. Joshua Evans of Greenbrier has confirmed he is considering the race. Roberts formerly represented the 18th Senate District, but lost his position last November when Robertson County was moved to the 25th District following redistricting. He was elected in March 2011 in a special election to fill the term of Diane Black following her election to Congress. Summerville upset longtime Democrat Doug Jackson of Dickson in 2010 in the old 25th District and has already said he plans to seek one more term next year. White has been the Republican nominee in the last two 69th District races for the Tennessee House of Representatives but lost to Democratic incumbent David Shepard both times. The 25th District now includes Dickson, Cheatham, Hickman, Humphreys and Robertson counties. No Democrats have announced plans to run for the senate seat at this time. The primary will be in August 2014 with the general election following in November.
