You can say all of that first paragraph. It's doesnt change that you're pushing a logical fallacy.
Sanders had no such problems in his first couple states, the factors that made South Carolina harder for his were regionally specific. You didn't see those kinds of numbers for Texas, as an example. Which again is why to Texas GOP massively supressed the nonwhite vote before ST, leading to a narrow Biden win.
The numbers that Sanders is getting now is entirely the result of (well executed) in party engineering and voters respond to the news of big wins and loses. Biden got a big bump for SC, a state he was always expected to win, which helped his position elsewhere, but it wasn't enough. So, the establishment closed ranks quickly which played well with late deciding voters, giving Biden an even bigger bounce from upsetting ST, which then has a ripple effect elsewhere. Votes aren't cast in a vaccum.
Sanders reluctance isn't about nonwhites or whites, it's about the ghoulish establishment that is incrementing everyone to their graves.
That's another fault of Sanders, he's too forgiving of people he believes to be friends even when they are opposed to him. I don't see how people were surprised by the establishment closing ranks post SC, following a good Biden win. Sanders never should have ever let on on attacking Bidens horrible record. It was a mistake that helped create a big enough SC win for Biden for the obvious to happen in an overly crowded field.
