I agree with you and I'd like to point out we've done studies and found that "Russiagate" in 2016 was a big nothingburger. https://www.washingtonpost.com/politics/2023/01/09/russian-trolls-twitter-had-little-influence-2016-voters/

Democrats don't want to hear it, though, because it's a very convenient excuse for their own failings. Just like them blaming Bernie Bros, despite Bernie supporters voting for Clinton in larger numbers than Clinton supporters voted for Obama 8 years prior.

They simply don't want to take responsibility for their own actions (and inaction).
