It's a general way of undermining truth by preventing people from focusing on facts.
The idea is to kick up dust, wear people out, and create a "bothsides" argument.
I'll attach an explainer for new followers.
Expect a lot more of this over the next 6 months. It's a way of controlling the media narrative.
(From a lecture that I linked to somewhere on my blog)
One way it will backfire is this: Most voters are just tired of it. Internal campaign polling is evidently showing that some people who say they approve of Trump are planning not to vote for him . . .
But they can still be tired of it and ready to vote him out.
Trump is also a natural.
My guess is that Trump imitates Putin and Orbán, and Bolsonaro imitates Trump.
It's all about power.
