We need a new constitution, badly. One that gives more power to the parliament, and less to the president. The current constitution is De Gaulle's creature, it was tailor made for him and simply doesn't represent people in today's political map.

The fact people don't feel their vote matters anymore is one of the main reasons far right is so strong right now. Macron has been elected with less than 28% of expressed votes on first turn of the election, yet he basically runs the place.

Changing constitution is actually in the left wing alliance's program. Except they want to do it democratically, by being elected into power, not through a revolution.
