Latest polls show a majority of Democrats prefer a presidential candidate who does not back the unqualified US military assistance to Israel.
The Reuters/Ipsos poll showed 56% of Democrats said they were less likely to support a candidate who backs such an aid.
Democrats also overwhelmingly said they wanted a presidential candidate who would call for a ceasefire in Gaza.
22 percent of Democrats in the poll blamed Israel for the killings in Gaza.
The poll results illustrate a potentially critical vulnerability for President Joe Biden, who has angered some within his party by supporting Israel.
Biden’s early and vocal support of Israel and his refusal to condition military aid on a change in Israel’s military tactics has sparked outrage among the Democrats.
The Biden administration has repeatedly sent munitions to Israel after promising “unwavering” support to Israel in the wake of the hostilities in Gaza in early October.
Washington has said it was still not drawing any red lines for Israel.
The Gaza death toll keeps going up. Famine looms. Much of the besieged Palestinian territory’s 2.3 million population has become homeless. And Israel has killed nearly 30,000 people there since.
The Reuters/Ipsos poll results come ahead of a close November election.
Biden has said an attack on the Palestinians waiting for aid in northern Gaza will complicate efforts to reach a ceasefire. “I know it will,” Biden told reporters when asked about the matter.
The president said a pause in the fighting would probably not come by next Monday. Biden had predicted so in remarks earlier this week.
Elsewhere, Biden said there are “two competing versions of what happened” during the attack and that the US was “checking” what had happened.
Witnesses have said the incident began when Israeli forces opened fire on a crowd that was waiting for food.
At least 112 Palestinians waiting for food aid were killed and 760 wounded after being shot at by Israeli forces.
Israel is using starvation as a weapon against the Palestinians in Gaza.
