Rep. Diane Black, R-Tenn., was declared the winner of her GOP primary around 8:40 p.m. local time Thursday.

Black easily beat former state Rep. Joe Carr, taking more than 60 percent of Republican votes.

"This is a great grassroots victory and a victory for the idea that we need a conservative Congressman who gets results," Black said in a statement. "We had a committed team of volunteers knocking on doors all across this district and we wouldn't have won without them."

Carr had sought to classify the three-term member of Congress as a Washington insider. Instead, Carr was criticized for running as a 6th congressional district resident despite his residing in Rutherford County — making him a carpetbagger to potential constituents.

Black sits on the Ways and Means and Budget committees.
