The North Carolina State Board of Elections has thrown out the results of November’s congressional race in the 9th District and ordered a new election, after more evidence came to light of a Republican effort to tamper with absentee ballots. The race had pitted Republican Mark Harris against Democrat Dan McCready. Harris initially appeared to be the narrow winner, but the race was never certified. For months Harris, who is a Baptist preacher, had insisted his campaign did nothing illegal, but on Thursday he called for a new election. This came a day after Harris’s own son—Assistant U.S. Attorney John Harris—testified that he had warned his father about hiring a longtime political operative who had a record of illegally collecting absentee ballots and in some cases filling them out in favor of Republican candidates. North Carolina’s Democratic Gov. Roy Cooper praised the board’s decision, saying it “sends a strong message that election fraud must not be tolerated.” President Trump—who has repeatedly warned about Democrats stealing elections—has yet to comment about the latest news from North Carolina.
