Outcumbent means: 1. People who hold the same or similar positions for longer periods of time than the current member of a political organization. An Outcumbent can still be considered an “incumbent” as per webstersoxford english dictionary definitions, but with more experience than their new incumbent. The Outcumbent does not challenge the incumbent in a particular office or position. That is just a challenger. (in Community Dictionary, added by Úrsula Méndez)
