France is stuck with Macron as President for the next couple years, but Le Pens young guy would become Prime Minister if they can get to 289 seats. Which gives orders to the military, I don't know. Which side do those in the military favor, I don't know. Hope the fence sitters note the lefty riots and wave the tri-color rather than the white flag Sunday! And that the tri-color is able to deal with the Je partita pas problem ("I won't leave") France's current hit song references. If those who like that gay Eurovision style actually combine with France's remaining norms maybe they'll be strong enough to take on the Islamic migrants.
From what I understand, in France the office of prime minister is a bit different than in other countries. The French president can pick whomever he wants as prime minister. No restrictions.
But the National Assembly can force a prime minister to resign by a vote of censure. So Macron could really gum things up if he wanted to. Appoint a centrist. If the National Assembly rejects him, appoint another centrist. Rinse and repeat.
If I’m wrong about the process here, I hope another Freeper corrects me.
