Aipac's influence is being tested in the 2026 US primaries, with the organization backing certain candidates and a progressive anti-aipac group also being active in the elections. The outcomes of these tests are unclear, with some reports indicating aipac-backed candidates have lost and others suggesting the anti-aipac group has also experienced a loss. The results may reflect voter attitudes towards Israel policy and the role of pro-Israel lobbying groups in US politics.
