RALEIGH, N.C. (AP) — A Republican primary runoff for a North Carolina congressional district on Tuesday could demonstrate yet again the strong influence former President Donald Trump has on GOP politics across the country.

Voters will choose between attorneys Kelly Daughtry and Brad Knott in the runoff for the reconfigured 13th Congressional District. Daughtry finished first, and Knott second, in the March 5 primary. GOP candidates for the statewide offices of lieutenant governor and state auditor are also on runoff ballots.

Trump endorsed Knott in April. Weeks later, Daughtry suspended her campaign, when early voting was already underway. The runoff continued on Tuesday with both names on the ballot. Knott must win the most votes to ensure victory; he’s reminded his supporters that they need to get out and vote.

If Daughtry were to win, but turned down the nomination, local Republicans would choose a replacement to take on Democrat Frank Pierce in November.
