Baptist minister Mark Walker (R) won the Republican runoff for U.S. House in North Carolina's 6th Congressional District Tuesday, turning back a challenger who had the support of the district's retiring congressman.

With nearly six out of 10 precincts reporting, the Associated Press called the race for Walker, who led Rockingham County District Attorney Phil Berger Jr., 57 percent to 44 percent.

Rep. Howard Coble (R), 83, is retiring at the end of this term. He endorsed Berger in the runoff and campaigned for him.

Walker will be a heavy favorite in November, given the district's heavy conservative tilt.

In the 5th District Democratic primary runoff, software developer Joshua Brannon defeated Gardenia Henley. Brannon will be a clear underdog against Rep. Virginia Foxx (R) in November.
