From the paper
"We assess the influence campaign aspired to help President-elect Trump’s chances of victory when possible by discrediting Secretary Clinton and publicly contrasting her unfavorably to the President-elect. When it appeared to Moscow that Secretary Clinton was likely to win the presidency the Russian influence campaign focused more on undercutting Secretary Clinton’s legitimacy and crippling her presidency from its start, including by impugning the fairness of the election."
Really, did the American public get influenced by Russian propaganda, and I have no doubt that many governments try to sway outcomes in their favor, do you really think Russia made that deciding vote? Was James Comey part of that?
Not entirely, no. But I do think they were a major factor. Of course Hillary's campaigning ended up being rather incompetent which didn't help either.
I think it was a confluence. As things usually are.
