Update: The parties of the left coalition have publicly reaffirmed their commitment to the coalition, sending a message to Macron that they will not govern under the liberals
I think RN/Ensemble coalition is unworkable, at least right now. Macron’s brand is staked too much in being the safeguard against the fascists, and I don’t see RN having any reason to hitch themselves to what has been a very unpopular administration. At the very least, these results mean that if either Macron or RN wants a functional right-wing government, the political costs are going to be severe.
