I do find it slightly bizarre that on HN, a website run by ycombinator i.e. Americana, seemingly the Russians always get the benefit of the doubt. Similarly with the President actually. The politics here is quite hard to characterise.
But I believe that, while legitimate election security researchers have all basically said there is no reason to doubt the election or believe there was any sort of widespread fraud or abuse (and such statements conform to what was said in court, where lawyers can face consequences for stating falsehoods), legitimate computer security researchers outside the Trump Administration have pointed to Russia on the Solarwinds hack, so I give that claim more credence.
