(Bannon may be popular, he still does not know what he is talking about.)
What do you think was the reasoning behind the assassination attempt if you don’t believe Bannon’s assessment?
For all we know, it was a car accident and the internet and twitter are exaggerating to the worst possible case with no evidence.
If it was an assassination attempt on Dugin, than he was the target. Except if that was the case, then "switching cars" with his daughter would have deliberately put her at risk, and that doesn't make sense. Someone trying to avoid assassination is not going to use their children as decoys.
So for now, a car accident plus the internet exaggerating and going with it is more likely the case right now.
