"Emmanuel Macron, the French president, has announced that he is dissolving the national assembly, and calling for legislative elections on June 30 and July 7.
The French president said that he can’t pretend nothing has happened, that the outcome of the EU election is not good for his government and that the rise of nationalists is a danger for France and Europe."
No, it isnt anything like that. The EU elections are different than the national ones and they arent explicitly connected in any way.
But they are implicitly connected. His party just did very badly in the EU elections. He could technically continue to govern till the next national elections or he could go to early national elections and ask the voters “hey, you didnt vote for me in the EU elections, do you still want me to rule this country or not? Please confirm that you still continue to support me”.
Basically Macron is saying “You just saw how fucked things are, with the far right getting over 30% of the votes in the EU elections. Vote for me or the fascists will win”. It is a move intended to rally the voters to his party but he also risks losing the elections(resulting in a fascist government).
As a general rule, in many countries the governing party does worse in the EU elections, because the EU elections are often used as an opportunity to vote for small/minor political parties or protest vote. The EU parliament isnt as legislatively relevant. They dont make laws, they just approve/reject laws proposed by the EU Commision.
The EU Commision isnt directly elected by the voters. The european country governments appoint EU Commission members(one from each country) and the EU parliament votes for the EU Commission leader. This is a point of contention.
Technically it is “democratic” because eventually everything comes down to either national european governments(who are democratically elected) or the EU parliament(which is also democratically elected). But many people think it is weird to have the most powerful EU institution appointed instead of directly elected. The procedure isnt as transparent as people would like and it involves a lot of backdoor “politicking”.
PS On the other hand, directly electing the EU Commission would give its members a lot more political power, basically on par or higher with the elected country leaders. Being directly elected greatly increases your political power.
