@Goddess the Russians likely changed zero votes, if any through hacking voting systems (with the possible exception of Florida).
They "hacked" the election via social engineering by creating fake accounts, fake people, and fake news on social media, swaying the opinions of the weak-minded, and also convincing people that they didn't need to get out there and vote. The results of the election were due, in large part, to those who voted for Obama, but did not vote at all in 2016 in swing states.
