I think that bitcoin is bit like anarcho-capitalist movement and I would not see any reasons why socialist like Le Pen would really like it(Yes they still can support some centralized adapt of blockchain technology). Still I would like to see Le Pen to be elected because I am anti multiculturalism and so. And after all she wont have much power over bitcoin.
It has no power. The election she will not win that's for sure. It can take you to Parliament many members, but it is only in the event that the investigation against her does not prove her guilt. Who knows, maybe she will run away to Russia and we've never hear.
