Attempting to “hold Biden accountable” by supporting, advocating for, and voting for someone who has already gone on record as saying he wants to do even worse is probably not going to work out the way you think it will.
I understand the position that people are in. It’s pretty much Sophie’s Choice. Vote for Biden, who’s supporting an ally that is currently committing genocide, or vote for Trump, who says he’ll genocide harder. Or stay home and vote for nobody, and end up with Trump anyway. There’s no good options here. I get that.
Nobody wants to vote for a man who says “Vote for me and I’ll kill your wife”. But at the same time, the counter to that isn’t to advocate for the opponent who’s saying “Vote for me and I’ll kill your wife, your kids, and I’ll piss on your dog while I’m doing it.” I’m not saying I know what the best option is, but I know that Trump of all people certainly isn’t it and will just make the problem much worse.
