And it started right after Trump won. Before that night the wisdom was exactly the opposite: that our elections can't be hacked, and we shouldn't believe claims about it.
Then Trump won and created mass hysteria in the political community, then the FUD went full steam ahead about Russia.
Instead of talking of the contents of the leaks, all we now can talk about was that there was a leak – and, oh – it was Russia hacking! (But don't discuss the details in the leaks, though. Instead pivot the discussion to malevolent hacking.)
I'm extremely skeptical Russia and their paltry spending had any effect on the election. Clinton and Trump were well known in this country long before the election anyhow. Clinton had a close relationship with Russia for that matter. And domestically Clinton/Trump and U.S. stakeholders spent billions of dollars to sway public opinion. Russia can't compete with that.
