How have the political parties of the United States responded to a shifting public opinion on Israel?

The current genocide of Palestinians and the future of the American relationship with Israel has become a litmus test that has stretched the Democratic and Republican Parties alike to their absolute limit. On the right, figures like Nick Fuentes and Tucker Carlson have spearheaded the anti-Israel wing of the Republican Party, often channeling the persecution of Christians to rally young conservatives, particularly Catholic and Orthodox Christians. Simultaneously, the surge of Democratic Socialism and explicitly anti-Israel candidates winning seats throughout the country has put Israel in the crosshairs of the further left wing of the Democratic Party, a group that is often in conflict with the traditionalist party of Chuck Schumer and Hakeem Jeffries. {¹, ²} The moderate New Democrats and Blue Dog caucuses of the Democrats are still largely Zionistic organizations, with the leader of the Blue Dog caucus Rep. Marie Gluesenkamp Perez having accepted close to a quarter of a million dollars from Pro-Israel PACs thus far {³}, and Rep. Brad Schneider of the New Democrats being closely tied to AIPAC itself with over half a million dollars in donations from the super PAC/affiliates. {⁴, ⁵} While support for Israel remains high among American Jews with 88% supporting the continued existence of Israel as a Jewish state, only 37% of the Jewish American population identify as Zionists. {⁶} This is a trend most clear among the Democratic base and has seemed to cause a dramatic, if not largely symbolic shift in the  policy of the left wing. On Wednesday, July 22nd, 103 House Democrats and 1 Republican voted to block all future defense funding to Israel through an amendment that was proposed by Republican Thomas Massie who recently lost reelection for his seat in Kentucky largely due to his anti-Israel stances. {⁷} The proposal failed with the remaining half of Democrats and all but one Republican voting against the amendment. {⁸} While the popular support for the state of Israel has declined sharply, it appears that the support of elected officials remains high with only a vocal minority of almost exclusively Democrats expressing dissent. Whether or not the United States government will remain devoted to Israel is in the hands of the voters. With November right around the corner, a new slew of anti-Israel candidates are in the running, most notably Abdul El-Sayed in Michigan, Melat Kiros in Colorado, and Troy Jackson from Maine, all Democrats aligned with the Progressive wing of the party. Whether or not the Republican Party will have an anti-Israel wing that is not rooted in conspiratorial anti-Semitism may be a breaking point for Republican voters in the next few cycles.
