Barrow won re-election to a fifth term last year even after state Republicans had redrawn the district to favor a GOP candidate.
“I’m grateful for the encouragement I’ve received from folks all across the state of Georgia, but I’ve decided that I will not be a candidate for the Senate in 2014,” Barrow said in a statement. “I enjoy my work on behalf of the folks in the 12th District, and I look forward to continuing to serve them in the House of Representatives.”
There are no announced Democratic candidates for the seat now held by Republican Saxby Chambliss, who is not seeking re-election. Michelle Nunn, daughter of former Democratic U.S. Sen. Sam Nunn, has expressed interest.
Three Republican representatives – Jack Kingston, of Savannah; Paul Broun, of Watkinsville; and Phil Gingrey, of Marietta – have announced plans to seek the Senate seat.
