It follows a trend in the EU Parliament moving away from left-center left parties and more towards right wing, anti-immigration parties. All across the EU solid right wing parties won pluralities in member states. Macron's center left party got pounded, no lube style in the election so he called a snap election. Snap elections happen when you have upsets like this as a way of the ruling party to maintain legitimacy in the face of overwhelming opposition. I explained it to my husband that it's a way to keep your head on your neck.
