Not really, since the President can dissove the National Assembly.
But, in such situations, never does so except after he himself has been reelected. For a reason, too - precedent from the Third Republic is that, if he does so and doesn't get a majority of his supporters in, he has to resign.
Attemping to use a precedent from the
Third Republic, which voted itself out existence, with some help from the Germans, in 1940 and applying it the
Fifth Republic is stretching things beyond the breaking point. The role of the President, in terms of the constitutional aspect , is very different today.
The most notable resignation, De Gaul, was triggered by the loss of a public referendum, not by anything that happened on the floor of the National Assembly
1. The President appoints, at his own discretion, the Prime Minister and can dismiss him. This is not a ministerial act or a formality, but a purely personal choice (As was Chaban-Delmas in 1972, after received a vote of confidence from the National Assembly).
2. He can dissolve the National Assembly, the only limitation being he cannot dissolve it twice during the same year. While he must "consult" with the presiding officers and the PM, their approval is
not required.
3. Many of the legislative procedures, such as budgeting, can become law, even if not directly voted on by the National Assembly.
The National Assembly is weaker than the US Congress and certainly much weaker than the UK House of Commons or the Bundestag.
A strong legislature is
not the hallmark of a strong government.
