The charge is not, and never has been that Russia changed any vote totals, although there are indications that they attempted to mess with voter registration systems. That could be just as damaging if it succeeded, which I'm not sure we know conclusively. The charge is that Russians committed criminal attacks against the DNC and the DCCC for the benefit of the Trump campaign. If Trump officials participated in that activity, they may have committed crimes in order to win the election.
IMO, the "Russia didn't change the votes" is an intentional deflection to take the focus off what Russia did. They clearly *influenced* the vote by use of info that was illegally obtained that cannot, to my satisfaction, be verified. Trump egged them on and encouraged them by saying they would be heavily rewarded.
It is looking more and more like voter registrations were tampered with along with the disinformation campaign towards HC on behalf of Trump. Outside of all the connections between those around him and Russia, what leads me to a one hundred percent certainty that Trump colluded with the Russians are his own words.
