According to a news report on Sunday, an investigation by the Democratic National Committee to discover what went wrong in the 2024 presidential election found that Kamala Harris lost because of her support for Israel and the Democratic Party policy on the Gaza war.

DNC Chairman Ken Martin ordered the investigation but said he would not publish the findings because it served no purpose.

The DNC “completed a comprehensive review of what happened in 2024,” he said in December. The organization was “putting its learnings into motion.”

“Here’s our North Star: Does this help us win?,” he added. “If the answer is no, it’s a distraction from the core mission.”

Representatives from the IMEU Policy Project, a Palestinian advocacy group, met with the DNC and told the DNC that the party lost the election because of Harris’ policy on Gaza. The DNC confirmed that its own findings matched that conclusion. IMEU accused the DNC of keeping the report secret because of its potentially explosive findings, which the DNC has denied.

Divisions over Israel policy within the Democratic Party have created tension between the far-left progressive flank of the party and the moderate Democratic wing. Harris tried to strike a balance between sympathy for the people of Gaza and support for Israel, but while she didn’t break with Biden on Israel, she took a harder stance. This may have cost her votes with swing voters and moderate Jewish Democrats who are pro-Israel. On the other hand, the progressive left that is virulently anti-Israel felt she didn’t go far enough, costing her votes with that demographic as well.

On her book tour for her memoir describing the events of her presidential campaign, Harris said that the Biden administration should have more forcefully criticized Israeli Prime Minister Benjamin Netanyahu and shown greater empathy for the people in Gaza.

In her book, 107 Days, Harris wrote that she believed her support for Gaza cost her votes. She said that she had urged Biden to show more sympathy for the people of Gaza and that his unpopularity, which she partly blamed on his stance on Israel, hurt her electoral prospects.
