North Carolina is gearing up for a redo election in the 9th District, which will likely include a new primary, too.

The last rerun of a general election for a House race was in 1975 in Louisiana. But when it comes to primary redos, a 1976 race in New Jersey offers some striking similarities to what’s already happened and what could happen in the Tar Heel State.

The North Carolina State Board of Elections on Thursday unanimously made the call after Republican nominee Mark Harris made a stunning reversal. Taking the stand after lunch on the fourth day of the board’s evidentiary hearing into election fraud, Harris proclaimed it was time for a new election. Up until that point — indeed hours earlier — he and the state GOP were urging the board to certify his 905-vote lead over Democrat Dan McCready from last November.

Numerous witnesses testified throughout the week that an operative who worked for the Harris campaign, Leslie McCrae Dowless Jr., ran an absentee ballot collection operation, which is illegal in North Carolina. Harris’ own son testified to having warned his father about hiring Dowless for that very reason. But his father, believing his son to have a “taste of arrogance,” ignored his concerns about Dowless.

And so Harris and his legal team were forced to reckon with the fact that the tampering with absentee ballots — whether Harris knew about it or not — called into question the Republican’s narrow lead.
