It’s always wise to check and see who owns the politicians you might be thinking of supporting. From Eric Zuesse at strategic-culture.org:
Some of the top owners of America’s President-Elect Joe Biden are entirely secret because a corrupt U.S. Supreme Court, in the infamous 2010 Citizens United case, encouraged not only corruption but corruption that’s entirely secret or “dark money.” However, most of the individuals who purchased Biden to become the U.S. President did so under the previously existing laws, which require public reporting of their donations.
Here, then, are the top ten publicly known donors to the Biden campaign, but these are all via some sort of Political Action Committee or PAC, and therefore most are in conjunction with other billionaires and centi-millionaires, instead of entirely solo donations:
