Scott Colom is set to become Mississippi’s first Democratic senator in nearly 40 years and its first Black senator since the post-Civil War Reconstruction era.

Colom, a 43-year-old district attorney, prevailed over Republican incumbent Senator Cindy Hyde-Smith in perhaps the most extraordinary seat flip of an already extraordinary US midterm election, in which Democrats crushed the Republicans to reclaim the majority in both chambers of Congress.
