Not really. So far the biggest fundraiser in the Democratic primary has been Bernie Sanders and he has raised most of his money from small money donors. So it's absolutely possible to raise money without using one's own money or taking bribes. And even if a candidate raises money from a 100 billionaires, that's better than one billionaire. The more people you raise money from the more likely it is that those people have conflicts with one another that can then balance one another out. A single billionaire financing their own campaign is just too much centralized power for my tastes, even if I trust that billionaire and generally like his policies. Power corrupts.
