If Biden loses, you can be certain, they were not responsible, they are most likely less than 1% of voters

Nah, they'll blame us the same way they blame us for losing the 2016 general election. We are simultaneously too small to matter but able to turn the tide of the largest election in the United States.

The left got so close to taking the DNC in 2016 they had to go to court to affirm their right to tell the left to eat a dick regardless of voters or donations, and now they're pushing legislation to strip the red tape from taking away nonprofit status from leftist orgs. Dems are running scared and it has their faschie flag flying high (see op disinformation campaign claiming anyone who dislikes biden is a 'tankie')

Of course, even though they've spent more time attacking the left than they EVER have Republicans they'll be happy to place the singular blame on us then march further right so they can shocked pikachu when the left doesn't vote for them then either.

This vote is far too important to protest vote. Especially now that I live in a swing state.

So, take this point of view as what it is: a view on the situation from an outsider, I am not American, I am a German communist. While I do probably look more closely at American politics than most likely the average American simply from being interested in politics to a pathological degree, I might not have the full picture of an American who is also as interested in politics.

I think in this particular moment, as much as the Democrats do their best to antagonise you, as much as you are correct that someone like Biden will continue with the same status quo bullshit that created the situation to begin with, as much as he won't be helping the people suffering from (neo)-colonialism in a meaningful way overseas - I don't think that this particular election is the time to vote third party. The chance may come, and best then to do it not as individuals based on your personal conscience, but as an organised group, with concrete messaging communicated. And even in other elections and outside this vote, organising for a third party - while I personally don't have a lot of hope for electoral politics - is certainly better than investing energy into the Democratic party, whose supporters seem to have no problems spewing hatred towards you for not agreeing with their party line and view of reality.

But I think underestimating Trump could be genuinely dangerous. Not because he will "ruin America" or anything like that. Simply, because he will be in a position to dial up repression, potentially leaving you with a situation in 2-4 years, where the party you voted for has to move underground, either having gotten outlawed or further marginalised and infiltrated. The situation looks critical enough to me, that under a Trump presidency, unions and leftist orgs will face open persecution much more than under someone like Biden - who is admittedly bad enough. Persecution up to outright criminalising them, to encouraging right-wing militias to kill their members with a slap on the wrist as a consequence or no legal repercussions at all. Yes, I do think that is unfortinately a realisitic possibility. And at this point, I don't think leftist orgs in the US have the resilience yet to efficiently organise in the underground.

That being said, I won't tell you a vitriolic "you will be at fault" if you choose to vote and organise as you want to. I do also see advantages, like getting visibility for your issues and potentially by reaching certain threshholds getting public funding support and the likes (that exists in the US too, right?). But I'd still advise it in this election - as shitty and cynical as it is - to vote for the old fart that doesn't swing the whip of the state as hard on your back as the one that might outright strangle you with it. Getting a proper communist, grassroots organisation running in the United States is important for the whole world, and I fear it will be impossible, or at least much, much harder under Trump (mostly, again, because there are no proper structures in place to move into illegality and organising underground, from everything I can tell.)

How does de la Cruz intend to stop arms shipments without any congressional representation to push legislation to do so?

If Congress says money must be spent on sending Israel weapons, then the president has to follow that in some capacity. The president could try to stop shipments, but that would result in a swift court case, and the president would be compelled to continue sending weapons. The executive branch has discretion in how to do so, but it unfortunately does not have the authority to end it.

You need Congress if you're going to stop all shipments. Alternatively I suppose you could try to have the judiciary in your favor, but that means de la Cruz now needs the Supreme Court on her side.

It's a complete misconception in American society and politics that the president can do anything. They're certainly the most powerful single individual, but Congress is still much stronger.

The Party for Socialism and Liberation would be much better served trying to win Congressional races so they can push for bills to end weapon shipments. If they could take a number of strong Republican districts with their message, it would give them a lot more influence.
