when does the incumbency advantage tend to be at its lowest
Incumbent However, there exist scenarios in which the incumbency factor itself leads to the downfall of the incumbent. Popularly known as the anti-incumbency factor, situations of this kind occur when the incumbent has proven himself not worthy of office during his tenure and the challengers demonstrate this to the voters. An anti-incumbency factor can also be responsible for bringing down incumbents who have been in office for many successive terms despite performance indicators, simply because the voters are convinced by the challengers of a need for change. It is also argued that the holders of extensively powerful offices are subject to immense pressure which leaves them politically impotent and unable to command enough public confidence for re-election; such is the case, for example, with the Presidency of France.[7]
