You can certainly argue that the Democrats failed to inspire and move the left whereas Trump succeeded with the right, although Trumpists seem to be regretting it more each day. This isn't a political conflict between rural and urban, left and right (there is no actual left in the US outside of social media) or even proles vs elites, but between establishment elites and outsider elites - and Trump represents the former, and Elon the latter.

But you can't rationally argue that Trump's success is due to an overwhelming repudiation of leftism from the masses. You will regardless, ad nauseum, because you're a Trump and Elon stooge. But the math just doesn't math.
