CNN's Harry Enten runs the numbers on special elections, including TN

"If in fact you had a thirteen-point shift like we saw in Tennessee, and you applied that to the 2024 presidential map, we are talking about a gain for Democrats of north of forty seats," says CNN chief data analyst Harry Enten, running the numbers on last night's special election in Tennessee's Seventh District. John Berman also speaks with CNN chief political analyst David Axelrod. #CNN #News
