Mississippi elects Democrat Scott Colom as state's first Black U.S. senator since Reconstruction

Mississippi Democratic nominee Scott Colom has defeated Republican Senator Cindy Hyde-Smith in Mississippi's closely contested U.S. Senate race after a prolonged ballot-counting process, giving the state its first Black U.S. senator since post-Civil War Reconstruction. Mr. Colom's narrow victory is a seismic shift in Mississippi, which has been controlled mostly by white conservatives for generations, and it yielded immediate echoes around the country. The outcome adds to a decisive midterm rebuke of President Donald Trump, whose party suffered defeats in several Republican-controlled states, and it will bolster some Democrats' argument that their future runs through the American South.
