Genocide is by far one of the worst crimes against humanity. If someone supports genocide they are morally corrupt to the core. They don’t care if you live or die. They will sell you out the moment it gives them a personal advantage. What kind of democracy forces it’s citizens to choose between two such people?
Americans generally don’t support genocide nor do they want a leader who would treat them like chess pieces. Unfortunately, the American electoral system is incapable of reflecting popular sentiment. If it can’t do that, then it’s not a real democracy. Change can only come to the US if people learn to wield their collective power in ways that don’t depend on the elections. Barring that, Americans are fucked regardless of who they vote for.
