Penultimate Amazing
Evidence for this part? It's not unthinkable, but... trying to create divisions between Ukraine and the US during the Obama Administration (as was also specifically said in 6) would seem to be far more indicated, with that work simply then being more emphasized and taken advantage of when Biden became candidate.
That is my opinion, based on my (admittedly incomplete) knowledge of US politics. As wareyn said, in 2014, Biden would have been a very likely Dem candidate for 2016 and while the Russians had other reasons to stoke distrust between the US and Ukraine, the fact that they used the Biden family as a conduit seems to me to lead to the obvious conclusion that they saw him as a threat to their plan to put their useful idiot in the White House.
