North Carolina Senate Race Upended by Sexting, Virus DiagnosisNorth Carolina's intensively competitive and expensive U.S. Senate race has been upended by personal and health disruptions that sent uncertainty through the campaigns and an electorate already casting ballots. Democratic nominee Cal Cunningham acknowledged and apologized for exchanging sexually suggestive text messages with a woman who's not his wife, but he said he wouldn't drop out of the race. And just a few hours earlier Friday evening, his opponent, Republican Senator Thom Tillis, announced he had tested positive for COVID-19. While the first-term senator said he had no symptoms, the news forced Tillis to cancel in-person events, and several members of his campaign staff headed into quarantine. "It's chaos," David McLennan, a political science professor at Meredith College in Raleigh, said in a Saturday interview. In the text message exchanges, Cunningham tells the woman he wants to kiss her and she says she wants to spend the night with him. The messages were first reported by the website NationalFile.com. "I have hurt my family, disappointed my friends, and am deeply sorry. The first step in repairing those relationships is taking complete responsibility, which I do," Cunningham said in his statement late Friday. Staying to fight Cunningham, who is married with two teenage children, added he's staying in the Senate race: "I will continue to work to earn the opportunity to fight for the people of our state." The race is the nation's most expensive Senate campaign and considered key to determining the power balance in the chamber. Democrats need to gain four seats in November to take control. Voting has been under way for four weeks in North Carolina, and 341,000 completed mail-in absentee ballots have been accepted and will be counted. Early in-person voting begins October 15. McLennan and Gary Pearce, a longtime state Democratic consultant, said it's unclear how much of an effect Cunningham's text messages will have on the election. "Most Democrats are really scared by it, but then you wonder: Has everything changed in the age of [President Donald] Trump?" Pearce said, adding the electorate's increased polarization since 2016 could lead many Democrats to stick with Cunningham simply because the party's victory is paramount. Timing A spokeswoman for Cunningham's campaign, Rachel Petri, confirmed the authenticity of the text messages on Saturday. It's unclear when the messages were sent, but at one point Cunningham says he's "nervous about the next 100 days," which could be a reference to the Senate election. One hundred days before the election would be July 26. An email trying to reach Guzman Todd at the California-based communications firm that lists her as an employee and voice messages left with what public records indicate are her phone numbers weren't returned Saturday. Public records show she had a Raleigh residence briefly until 2015. Guzman Todd is married to someone who has served in the U.S. Army, according to the NationalFile.com report. Cunningham, 47, is an attorney and Iraq War veteran who still serves as an officer in the U.S. Army Reserve. He served one term in the state Senate in the early 2000s and lost a Democratic primary runoff for U.S. Senate in 2010. As for Tillis, he said he has no symptoms but will be staying at home for 10 days. Cunningham tweeted that he wished Tillis a "quick recovery" and said he would get tested himself after the two men shared a debate stage Thursday night. No other debates are scheduled. The Tillis campaign, citing its own health concerns, deferred on Saturday questions about the text messages to Cunningham. National Republican Senatorial Committee spokesperson Jesse Hunt said Cunningham must disclose more so voters can decide his fitness for office: "These are very troubling allegations and Cal needs to be fully transparent with the voters of North Carolina." Tillis, 60, was diagnosed with the virus after attending the Supreme Court nomination ceremony in the White House Rose Garden for Amy Coney Barrett on September 26. The first-term senator didn't say in his statement where he believes he caught the virus but did say he had tested negative for the virus on the same day as the White House event. Advocates mask use Tillis was wearing a mask at the ceremony and has been among the most consistent Republicans to preach the use of face coverings. In late August, Tillis apologized for listening maskless in person to Trump's Republican nomination acceptance speech outdoors at the White House. The North Carolina Senate race is second only to the presidential campaign in terms of overall outside spending, according to the Center for Responsive Politics. More than $97 million has been spent by independent expenditure groups in the general election, center data says. Cunningham, who outraised Tillis during the first half of the year, announced this week that his campaign would report collecting $28.3 million in the third quarter — a record haul for any North Carolina candidate. Tillis' campaign hasn't announced his third-quarter fundraising totals.
