If and when Biden deals with Gaza, everyone with this mindset immediately needs to turn around and start sucking off Biden with previously unseen vigor and determination, otherwise this is only going to damage his chance of being elected.
There's tens of thousands of mostly children dead, and Israel is using famine and disease to wipe out the rest, no shit it damages Biden's chances if his actions come this late. Especially if Biden's answer to Gaza is ship Israel weapons more quietly while claiming to hold up shipments, while Israel starves Gaza out.
Then again, if Biden stops the money and arms to Israel, and sanctions Israel, and Trump responds by promising money and arms to Israel so they can resume the genocide, I don't see how anyone could not vote Biden.
