Mark Walker has defeated Phil Berger Jr. in the GOP runoff for the 6th congressional district.
Walker defeated Berger by a margin of 18,871 votes to 12,550 votes, according to unofficial final totals from the State Board of Elections.
Walker now faces a challenge from Democratic primary winner Laura Fjeld in November.
As the race between Berger and Walker drew to a close, the campaign turned particularly negative.
The negativity was evident in the campaign’s only television debate held by Time Warner Cable News in Raleigh.
The candidates’ views on repealing the Affordable Care Act, Immigration and Reducing Taxes were overshadowed by allegations.
Walker repeatedly asked Berger to admit whether or not his father, Phil Berger Sr., funneled $75,000 to a super political action committee to help Berger campaign. Berger called out Walker for linking him to the ethics violations case of Berger v. United State in 1935.
In the May 6 primary, Berger led the nine candidates running for the seat, getting 34.27 percent. A candidate must get more than 40 percent to advance.
Walker finished second, with 25.2 percent of the vote.
The seat has been held by Republican Congressman Howard Coble since 1985.
