You think the Democrats dropped Biden just because some big donations stopped? Not because that was a sign that was consistent with all the polls that showed Biden was poised to lose in a landslide? Not because the Democrats are motivated mainly to stop Trump from getting into the White House again and turning the country into a naked autocracy?

And you don't think Trump is beholden to big money? Part of Trump's mental disorder is that he wants to be admired by the rich and powerful. That's why he gave the biggest tax cut to the wealthy who don't need it. So in that sense he's beholden to the rich since psychologically he needs their approval. And Trump is nowhere near as wealthy as he says.
