It seems from the other threads, that Russia may have been using Trump to his advantage, and potentially exploiting some weaknesses of information. It just so happened that the information on Clinton was the only one that got leaked, due to the fact that they wanted Trump to win. It's clear that if they can rig one election in one of the biggest countries in the world, they can continue to do so in countries across Europe. Something that can be dangerous, not only for the US, but for the Western World as we know it.
I will be personally interested in seeing the effect they might have with Marine Le Pen, in France, and AfD in Germany.
