From a left-of-center perspective, I'd say as long as headlines are about tweets and high heels, sooner or later people will either burn out on the criticisms, or become desensitized. I think that emboldens his supporters. I believe that as long as the right can continue to define Democrats as "left" and left as extreme left, and further still extreme left as Antifa and BLM (the right's perception of these groups, that is), then Democrats = Antifa anarchists as far as the propaganda is concerned. If that perception can be stoked and maintained, I would not be surprised to see right-leaning moderates siding with Trump again either in sympathy or by a perceived underdog support. combine that with the complacent left-leaning moderates that never seem to get too worked up over anything, and I'm concerned. Oh. And add low level elections that get no Democratic backing to the mix. I derno.
That's not to defend Black's position. I think that's mostly just talk radio style rehash and doesn't make an actual argument. That's like someone saying a sheet of paper moved because of magic. No. I just turned the rotary fan on. No. It is magic, and the proof is because the sheet moved. It may happen, but the correlations made are not why.
I am concerned though, for different reasons.
