I very much doubt they're competent enough to pull something like this convincingly here in the US and avoid early detection and counter-intelligence response. Thus far no evidence whatsoever was presented that any of this was Russian, let alone state sponsored. That's either some truly elite level GRU work, to the standard we have not ever seen before, or there is, in fact, no "paid Russian trolls" on The_Donald. My opinion: there's no way in hell they could pull this off without getting noticed _well before_ the anointed Democratic candidate lost the election.
