American public support for Israel has fallen across nearly every political and demographic group, with the steepest declines coming from within the Republican Party itself, according to a new CNN analysis that paints a striking picture of how dramatically attitudes have shifted since 2022.

CNN chief data analyst Harry Enten found that among Republicans under 50, net favorability toward Israel has swung more than 40 points in four years — from +28 points in 2022 to -2 in 2025 and further down to -16 in 2026. Among moderate and liberal Republicans, who make up roughly a third of the party’s base, net favorability dropped from +26 in 2022 to -9 in 2026.

The numbers are even more pronounced among younger male voters — a demographic that was central to Donald Trump’s 2024 coalition. Favorability toward Israel among men under 50 collapsed from -3 points in 2022 to -47 in 2026, a 44-point decline.

On the Democratic side, opposition to Israel — long concentrated among the party’s progressive wing — has now spread to moderates and conservatives. Among non-liberal Democrats, net support for Israel dropped from +3 in 2022 to -55 in 2026, a nearly 60-point swing in four years.

Enten attributed the shift largely to the ongoing Israel-Gaza conflict, particularly Israel’s military campaign following the October 7, 2023 Hamas attacks, and pointed specifically to Israeli Prime Minister Benjamin Netanyahu as a contributing factor in eroding American support.

The political consequences are already visible. Rep. Thomas Massie of Kentucky, one of Congress’s most outspoken critics of U.S. support for Israel, is currently favored to win his Republican primary despite opposition from both Trump and major pro-Israel groups, with forecasters giving him roughly a 71% chance of securing the nomination in Kentucky’s 4th District.

Public interest in pro-Israel lobbying has also surged alongside the declining favorability numbers. Google searches for the American Israel Public Affairs Committee, better known as AIPAC, rose 363% in 2026, reflecting heightened scrutiny of the organization’s political influence.
