A recent analysis reveals a marked decline in American public support for Israel, cutting across political affiliations and demographic groups. This trend is largely attributed to the leadership of Israeli Prime Minister Benjamin Netanyahu and the ongoing Israel-Gaza conflict.
Among Republicans under 50, net favorability toward Israel has plunged dramatically, falling from +28 points four years ago to -2 in 2025, and further dropping to -16 in 2026. This represents a decline of over 40 points. Moderate and liberal Republicans, who constitute about one-third of the party base, have also shown decreased support, with net favorability sliding from +26 points in 2022 to -9 points in 2026.
Political developments reflect this shift, exemplified by Thomas Massie, a Republican known for his critical views on Israel. Despite opposition from former President Donald Trump and pro-Israel groups, Massie is favored to win a competitive primary in Kentucky’s 4th District, with an estimated 71% chance of securing the nomination.
Support among younger male voters, a crucial segment of Donald Trump’s 2024 coalition, has also eroded significantly. Favorability toward Israel among men under 50 dropped from -3 points in 2022 to -47 in 2026, indicating a substantial shift in this demographic.
On the Democratic side, opposition to Israel, once mainly confined to liberal voters, has expanded to include moderates and conservatives. Among non-liberal Democrats, net support declined sharply from +3 points in 2022 to -55 in 2026, a swing of nearly 60 points.
Experts link these changes primarily to the ongoing conflict between Israel and Gaza, especially following the October 7 attacks and Israel’s military response. Netanyahu’s leadership is also seen as a significant factor influencing the decline in American public support.
In a related development, public interest in pro-Israel lobbying has surged, with Google searches for the American Israel Public Affairs Committee (AIPAC) increasing by 363% in 2026, reflecting heightened awareness and engagement on the issue.
