On the issue of Gaza, Biden is dramatically out of touch with the voters he needs to win re-election. If he will not be moved by morality to stop his support of this war, he should be moved by vulgar self-interest. Gaza is not a distant foreign conflict: it is an urgent moral emergency for large swaths of voters. Biden will lose those voters – and may indeed lose the election – if he does not cease his support of these atrocities.
Biden has that rare opportunity in politics: to help the country, and himself, by doing the right thing. But he must do so now. Both the Palestinian people and his own election prospects are running out of time.
That really only applies if your vote can change the election which isn’t going to happen outside of the maybe 4 swing states.
With your same logic if your voting for Biden in one of the states he’s guaranteed to win or lose then your morally supporting a genocide for no actual change.
