Not to be (too) argumentative, but what happened last night suggest there's a 50/50 chance of Missouri going blue in the November election? Texas results, maybe, in terms of enthusiasm and turnout? I guess I'm just not seeing it yet. Probably know more after Mo's primary next week. I would suspect a huge win for Biden, and if so, think your theory could hold water. If Bernie is competitive here, then I think Mo stays red in November.
I think the good ol' boy, redneck and racist/bigot contingencies are just too strong down here for a dem president to win but who knows. I would admit that only Biden (of all the dem candidates) could pull it off if it were to happen.
