“The voters said no to radical, liberal polices pushed by today’s Democratic Party,” Mr Bishop said in a victory speech on Tuesday night.
The new election was called by the state’s board of elections after a Republican consultant was accused of manipulating the November vote by illegally collecting, falsely witnessing and otherwise tampering with absentee ballots.
The Republican candidate at the time, Mark Harris, maintains he was unaware of any alleged fraud in his campaign.
In his concession speech, Mr McCready referred to the ballot fraud investigation that brought about the special election. “The people of North Carolina stood up and we faced down the full force of election fraud and voter suppression,” he said.
“When the people in power sought to silence the voices of the voters, stole their ballots, forged signatures from them, filled in vote choices for them.we fought back and we won.”
In a separate development, Mr Trump has denied reports that the White House urged a federal agency to repudiate weather forecasters who contradicted the president’s claim that Hurricane Dorian would hit Alabama.
Mr Trump was responding to a report that his chief of staff, Mick Mulvaney, directed the National Oceanic and Atmospheric Administration to publicly criticise its Alabama weather office for stating that Alabama was not at risk.
