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.
