Biden has gaffes left and right, and yes, does plenty of self harm. Then again, so does Bloomberg....maybe not as often (who knows...) but we're not going to be hearing much about those at all.

What people often fail to realize, is much of the interference isn't "fake news", it's merely subtlety directing people what to pay attention to. The troll farms selectively push and republish certain content (even things like the above videos) while they push positive content for "their guy", coupled with strategies to reach their targeted group (democrats, right now). Subtle influences end up having cascading/avalanche effects the more they do it - they start the focus, and their follows share and retweet and it cascades. When it comes right down to it - with enough focus - any of us would look like jack-wagon imbeciles too. The stupid shit we say, stumbles we take, and mistakes of speech we make are ignored.

Selectively focus attention on anything and the social-media American's will run with it like a boulder in an Indiana Jones movie.

If people discount the sheer power of this machine, take a moment to consider that the American belief of "Nuclear Winter" is a farce started entirely by a single, small russian op to plant the idea into a single american publication; prior to the internet really being a thing. That was hard. Yup, if you're not aware, "Nuclear Winter" isn't a real thing. Ruskies wanted America to think the world would end as we know it.

Now their minimum wage jockies can do that shit left and right.
