NORTH CAROLINA’S 9TH CONGRESSIONAL DISTRICT (open)

Current polling: Mark Harris (R) 45, Dan McCready (D) 44 (NYT/Siena, 10/30)
Why this race matters: In May, McCready celebrated an overwhelming victory in the North Carolina 9th District primary, earning more votes than every Republican candidate combined. The enthusiasm in this area of the state is palpable, and McCready’s race, which was rated “safe Republican” a year ago, has been upgraded three separate times to a “toss up.” There’s just something about this Marine Corps veteran that voters seem to identify with, and his significant fundraising hauls have allowed him to stay up on the airwaves.
