The oldest man in the Senate will be replaced by the youngest man in the Senate after 36-year-old Carte Goodwin is sworn in on Tuesday in the West Virginia seat formerly occupied by recently deceased 92-year-old Robert Byrd. Goodwin is a former counsel to Democratic governor Joe Manchin, who appointed Goodwin as a placeholder until he runs for the seat himself in a special election expected to be held in a few months.
