Open Seat refers to an elective office during an election cycle in which no incumbent office holder seeks re-election. Given the incumbency advantage in legislative elections in the United States and Japan, such races typically offer non-incumbents their greatest probability of winning office. As a consequence, the electoral competition for open seats is often more intense than in other races.
