It's honestly a pretty safe bet to think that both liberals and leftist's positions are being amplified and twisted by propagandists. I'm a queer leftist. I know how much damage another trump presidency would be for my community, but at the same time, I know how harmful a current Biden presidency is to Palestinians. My life isn't more important than theirs, so I refuse to look at this like I'm some outsider looking in since I'm biased towards my own comfort. Since trump isn't an option and since relying on 3rd parties to be our saviors is unrealistic, more strategic actions must be made (like lying about abstaining your vote for instance). Hell, a ton of leftists aren't even in states where it would even matter who they vote for, so all they have is their voice to try to change current policy rather than change to a different president (3rd party) with different policy.

Poisoning online discourse of Biden's specific policies until his campaign team determines that he needs to change things to win the election is about the only thing likely to move the needle for leftists living in deep red or deep blue states. So far, Biden's team has shifted to being vocally against Israel's actions in public but still sending funds and weapons sales regardless of the harsh words. But harsh words aren't making a difference since Netanyahu had no issues invading Rafah. So more pressure has to be placed on Biden (through electoral leverage) until he acts in such a way that it makes a real difference. There's still time for Biden to reverse course, to stop threatening the ICC, to stop vetoing UN resolutions, to stop shipping weapons regardless of our trade deals with Israel. That's the leverage he has and electoral strategy is our leverage. Assuming everyone is acting in bad faith denies discussion about what actually should be done in the meantime while we see what kind of Biden is on the ballot this November.

And yes, some leftists are so livid over our role in horrors around the world and want to burn things to the ground since more people would be happier in the world without the US policing them, instigating coups, exploiting the global south and prisoners for slave labor in this country, as well as countless other reasons this "democracy" probably isn't worth saving. And while I also think America (as well as pretty much every global superpower out there) are genuinely evil, tearing down this system right now probably wouldn't really help out Palestinians in the short term (short term being important because there's half a million people starving to death who could be helped).

The real issue here is that AIPAC is known to heavily support candidates against anyone who isn't staunchly pro-israel (they spent $4.5 Million on Katie Porter's rival in California and helped get Maxine Dexter seated in Oregon with the help of republican donors). They would likely push anti-biden or pro-trump just to maintain their singular goal. AIPAC is also currently trying to unseat Jamaal Bowman (D-NY) from the House and replace him with someone who is pro-israel. If AIPAC has enough power to control the sway of elections, they definitely have more sway than leftists online ever will. Though, if Biden reverses course (initiating actions from AIPAC) then loses the election, leftists will be blamed while AIPAC will be largely ignored.
