@cbsnews: Democrat Scott Colom defeated GOP Sen. Cindy Hyde-Smith in the Mississippi Senate race, CBS News projects, delivering Democrats an eighth flipped Senate seat after the dramatic race had been up in the air for days. Colom, 43, is a district attorney and seventh-generation Mississippian. He campaigned on cost-of-living and healthcare issues, while pledging to deliver for the Magnolia State where he argued Hyde-Smith hasn't. He will be the state's first Black senator since Reconstruction. #History #politics #mississippi #election
