On May 17 and 18 the Arab American Anti-Discrimination Committee and the Truth Project asked 36,139 Arab Americans and “allied voters,” "Who are you voting for in November?" 2,196 people responded.
Then a couple weeks ago a NYT poll "found Trump leading among registered Middle Eastern, North African or Muslim voters in the swing states, with 57 percent saying they were planning to back him in November. Only 25 percent said they were supporting Biden."
Sure and I imagine most all of that decline is due to the Israel/Gaza war. That he's gained 8% back since it started, while being heavily criticized for his handling of it, seems like a win.
