The pro-Israel lobbying group AIPAC has invested a record-breaking amount of money into Michigan's Senate primary. This significant expenditure serves as a critical test of the organization's political influence within the state. AIPAC is throwing its full weight behind Democratic candidate Haley Stevens. Stevens is currently facing a challenge from Abdul El-Sayed, a Muslim progressive. This political battle is taking place in Michigan, which is home to the largest Arab community in the United States. The contest highlights the tension between pro-Israel interests and progressive Muslim political movements. The outcome will likely signal the extent of AIPAC's impact on electoral results in diverse states.
