Biden is a self-admitted Zionist, isn't he? It's not a pejorative to him, or any establishment politician. It's ironic considering Ireland and the Irish people have been vocally calling it a genocide since the beginning.
Still, there are more proponents of a ceasefire on the Dem's side than the Rep's, especially down ballot. If the Dem's capture both House and Senate, there might be enough noise to actually pressure towards a ceasefire. Go vote.
Sorry if I was unclear, I meant that you should be voting down ballot for people that are vocal about putting pressure on the higher ups, or have the power to put in local reforms that have cascading effects to a wider state/national level. Your state representatives, your municipal councils of government, your schoolboard representatives, a lot of places have those elections tied to presidential elections, and low voter turn out hurts a LOT because those are less gerrymandered and more likely to swing progressive if more people turn out to vote.
Many people think that voting for the "right" presidential candidate is how things change, but there is just too much money concentrated at the top for it to ever happen post-Jimmy Carter. They will always more likely be milquetoast centrists to outright fascists, depending on the party.
Of course this is all my opinion.
