It looks like much of this is down to two individuals called William Craddock and Jack Posobiec, both connected to the so called 'alt right', with early involvement fromm Russian linked sources
Yes, well, a hallmark of conspiracy theories is that they have more twists and turns than a Hollywood film with both never reflecting reality.
Still, no explanation as to the need for Russia to be trying to turn votes against leftist globalists in Europe and America.
And why wait to the eve of voting to leak material? It's well known that the left controls the media on both sides of the Atlantic and will matter-of-factly suppress stories or distract the populations with sports and celebrity gossip. It would have been far more damaging for any leak to be made earlier so the French public could learn about and absorb it to the point where the leftist media and their darling globalist candidate couldn't ignore it.
Also, nothing will weaken the West more than culturally dividing immigration and ultimately the trillions it will cost to fund it. It would make far more sense for Russia to support such candidates rather than nationalists.
As time goes on this "blame the Russians" theme seems more like sour grapes from a generation of Soviets and their descendants who made their way to the West and Israel after losing power in Russia and the former Warsaw Pact countries.
Globalism is nothing more than a rebranding of The Communist International and it is clear who supports it and why.
