This political action group sent out a survey to everyone who subscribes to their newsletter and the folks who are engaged with this anti-establishment political organization are gasp against the establishment candidates.

Calling this a survey is an insult to statisticians; at best this is a straw poll and doesn't provide any meaningful information about how these sentiments might be shared more broadly. Yes - Arabs mad, Biden bad, we know this with or without the survey, but it doesn't survey a representative (randomized) sample of Arab-American voters, so it's impossible to extrapolate the results at a state or national level.
