Actually this so called "hack" will most likely favor Macron.
Everyone is tired of the russians fake news and propaganda.
The mainstream media in France is working 24x7 to prop up Macaroni. It seems like someone from Macron's own team invented this hacking story. Anyway, why he is worrying so much, if he has nothing to hide?
Every person has the right to privacy. He must decide for himself what he needs to disclose and what is not. Why is it for him to decide hackers?
