The six-day poll, which closed on Monday, found a pronounced partisan divide on the issue, with 78% of Democrats supporting the idea, far more than the 41% of President Donald Trump’s Republicans who agreed.
Israel has long counted on the U.S., its most powerful ally, for billions of dollars a year in military aid and international diplomatic support. An erosion of U.S. public support would be a worrisome sign for Israel.
The poll was taken within weeks of three countries, close U.S. allies Canada, Britain and France, announcing they intend to recognize a Palestinian state. This ratcheted up pressure on Israel as starvation spreads in Gaza.
Britain, Canada, Australia and several of their European allies said last week that the humanitarian crisis in the war-torn Palestinian enclave has reached “unimaginable levels”, as aid groups warned that Gazans are on the verge of famine.
The United Nations human rights office said on Tuesday Israel was not letting enough supplies into the Gaza Strip to avert widespread starvation.
Officials at the Israeli embassy in Washington and mission to the United Nations did not immediately respond to requests for comment on the poll.
