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 the geopolitical matters is not the main thing i like about Melenchon. Yes, he is good at it, but over years France is fluid in their foreign policy, Macron talked big on Chinese Human right issues last term but when money talk comes, the dude still goes to Beijing to secure more contracts. Mélenchon's last election promised electoral reform and the dissolution of the 5e republic, which is needed and necessary, but I have yet seen a party that will dissolve the system that allows them to come to power in the first place.
