I assume your "abhorently evil" comment is based off support of the genocide in Palestine (which is a completely reasonable thing to describe as abhorently evil, I'm just being clear about my premise).

In which case, sorry, bad news, you can't have that. Your options this time round are genocide supporter or genocide supporter. Somewhere down the line, years from now, the US electoral system may have been sufficiently reformed to make third parties viable. But this year that's not going to happen.

So that decision is completely out of your hands. But here's what you do get to decide; you can have an outright fascist, leading a party of outright fascists who have openly publicised their plans to turn your country into a fascist theocracy. Or you can have the guys who strengthened workers rights and went after major companies for union busting, hit Microsoft for $20 billion in back taxes, had the FBI raid a major landlord for illegal price hikes, brought antitrust lawsuits against Amazon and several other large tech firms, and secured billions in aid for Ukraine in their fight for their freedom. And that is literally just a tiny sampling of the good things that Biden's government has done.

I don't even see how that's a choice. One of these two options is clearly and manifestly better than the other, no matter how disgusting it feels. A vote for Biden is not an endorsement of his position on Gaza. It is a tactical choice, nothing more. And if nothing else, its a tactical choice that will prevent the fascists from filling even more seats on the supreme court.

It sucks, but those are the only options. Sometimes life just be like that.
