So what are these Russians alleged to have done?  NOT actually anything to do with the election.  They are alleged to have hacked stuff and released it months and months before the election.   
The only effect that could have on the election is the decisions it led to among voters.  
The Dems have never challenged the authenticity of the material, so it would seem the voters made up their minds based on the facts.  
Even IF it had been Russia, the only influence on the election was indirectly, by putting the truth out.
