WAS RUSSIAN MEDDLING ENOUGH TO SWING IT FOR BOMBER TRUMP?

So Mueller has concluded what most of us knew/suspected: Russia did meddle and nobody on Team Trump knowingly colluded.

But was the Russian meddling enough to swing it for Trump?

The troll factory may have had some influence.

But it was that Comey letter about Clinton emails that swung it. Clinton was a few points ahead when Comey wrote that letter (which he need not have written). But after its publication Clinton immediately lost 4 to 5%. When Comey stated the day before the election there was nothing suspcicious in those Clinton emails it was too late for Clinton. She regained only about 1 to 2%. As a consequence Trump won. The Russian troll factory could have amplified the suspicion about Clinton, but by how much? How could that be measured?
