Barrow’s victory is something of pick-me-up for the fiscally conservative Blue Dog Coalition, of which the Georgia Democrat is a member. 

Republicans have already defeated two other Blue Dogs, Reps. Ben Chandler (Ky.) and Larry Kissell (N.C.), this year, and the coalition saw its ranks decimated in the 2010 GOP wave. 

Barrow will now remain the only white House Democrat serving in a wide swath of Deep South states, including Alabama, Georgia, Louisiana, Mississippi and South Carolina. 

In the race, Anderson cast himself as a conservative that better fit the redrawn district, and hit at Barrow for opposing the House GOP’s efforts to repeal the Democratic healthcare overhaul.
