I stopped participating in Pres. Biden’s national finance committee because I could no longer support his feckless approach to ending the war in the Gaza Strip, where Israel continues to use US weapons every day to kill innocent women and children... Now I’m cautiously optimistic that Harris and Walz have the political space and resolve to do what Biden could not: make a fundamental course correction in how the US is managing dueling crises in Ukraine and Gaza... Biden’s unconditional backing of Israel sapped his support among demoralized voters like me who expected a baseline respect for international law and innocent civilian lives... Taking a clear moral stand now—backed by concrete steps laying out how she would lead the nation in a new direction—would allow Harris to reenergize support among voters likely to decide the outcome of the presidential race.
