They're "confident" of it. Who could doubt that?
Say for the sake of argument it's correct. When people say, hacked the election, was taking that literally and thinking something other than the DNC email hack was implied. Seems it's only inflated buzzwording. Don't think the DNC hack had any affect on public opinion or swayed voters from their party; it wasn't even really anything scandalous. My take on the paper, Russia did what they do, have done, and will continue to do, not only with the US but also other countries; though it was concluded the effort was greater this time. The social media aspect was particularly interesting, and not something previously considered; that some of the smear campaign tactics witnessed weren't necessarily the work of the republican party or supporting voters. Social media campaigns certainly could have affected pubic opinion, though impossible to measure. Up until the actual vote, Clinton was pegged as the winner from every reliable source of prediction.
