And like I said, a politicians first job is to get elected. And unless your whole party is corrupt and full of yes men, I president isn't an all powerful dictator. If pro-genocide Zionists vote and anti genocide people don't, then if course every politician is going to be pro Israel. All you do by not voting is reinforce the pro Israel position. Not voting means you're just as responsible for what happened then the people actively voting for genocide.
Kamala was a shitty candidate that completely failed to inspire the democratic based to show up to vote. But that's a completely different discussion.
