French Prime Minister Bernard Cazeneuve said the new extension was "absolutely indispensable in order to protect our citizens".
France is seeking to extend the state of emergency status implemented following the Bataclan terror attacks.
Parliament will vote next week on a six-month extension of a state of emergency to ensure the protection of upcoming presidential and general elections,
If passed, it will be the fifth since the extraordinary provisions came into place in the wake of the Paris attacks in November 2015.
Prime Minister Bernard Cazeneuve said public meetings and gatherings associated with the campaign "can unfortunately create a context of augmented risk of terrorist attacks for those who want to hit us at the heart of our democratic values and republican principles."
"It is thus necessary, in the eyes of the government, to include the whole electoral period in the renewal time that we ask for," he added.
The state of emergency was extended in July after scores were killed when a large truck plowed through a Bastille Day crowd in Nice in what authorities called a terror attack. It was followed by a thwarted ISIS plot to attack Notre Dame Cathedral in Paris.
