Nearly half of all House Democrats support ending aid to Israel. And with a new cohort of Democratic candidates who belong to the progressive left flank of the party poised to win the midterm elections, that balance will tilt to the anti-Israel side.

The House voted Wednesday overwhelmingly, 314-104-10, to defeat an amendment to the appropriations bill proposed by Thomas Massie (R-Ky.) and Ro Khanna (D-Calif.) to end military aid to Israel. Democrats split fairly evenly over the vote, with 103 voting against the amendment, 98 voting for it, and 10 voting present. Massie was the only Republican to vote to block aid to Israel.

The vote shows how the issue of Israel is changing the political dynamics of the Democratic Party. Leading the Democratic contingent who opposed the measure was Minority Leader Hakeem Jeffries (D-N.Y.), who wrote a letter yesterday urging his colleagues to vote nay.

Jeffries argued that the bill would restrict U.S. humanitarian efforts in the region and undermine the security of both the United States and Israel.

“It is overly broad in that it prohibits or would limit the use of funds for longstanding initiatives related to humanitarian aid, refugee resettlement, peace-building and U.S. Embassy operations,” Jeffries wrote.

The amendment “would restrict our country’s ability to confront Hamas, Hezbollah and other terrorist organizations in the region who are sworn enemies of both the United States and Israel,” he added.

“America’s commitment to Israel’s right to exist as a Jewish and democratic state and homeland for the Jewish people must remain ironclad,” he stated. “Equally significant, the United States must strongly support the creation of an independent Palestinian state that provides dignity, respect and self-determination for the Palestinian people,” he added, while calling for more humanitarian aid in Gaza and an end to settler violence.

House Democratic Whip Katherine Clark (D-Mass.) voted for the amendment, explaining that “the status quo is not tenable. We should not provide a blank check for military aid to any country that does not comply with U.S. law, interests and values,” Clark said. “The Netanyahu government has failed to meet that standard. I will be voting yes, not because I agree with the entirety of the amendment, or the GOP’s cynical motivations for its consideration, but because I believe we must change course.”

In a shocking turn, Nancy Pelosi (D-Calif.) also supported the measure, despite her current stated commitment to a strong U.S.-Israel relationship and past record of strong pro-Israel support, which shows that she consistently voted for military aid to Israel.

“The United States must be a force for security and stability,” she said. “The American people are rightly demanding an end to a perpetual cycle of war, and the Netanyahu government cannot maintain its current course. Therefore, while this amendment is ill-conceived, I vote yes for the message that it sends.”
