"Just like any other group of people, it is wrong to assume that Muslims in America are a monolith," he said. "Americans of Muslim origin come from different backgrounds, come with different values, and they vote for different reasons. And their reasons may not be any different than any other American's. You know, many people vote based on bread and butter, kitchen-table issues: jobs, education, taxation and certainly immigration."
In fact, Trump appears to have gotten more, not less support from American Muslims. Associated Press exit polls show 35% of Muslims voted for Trump and 64% for Joe Biden. A separate poll from a Muslim civil rights group found that 17% of Muslims voted for Trump, but that was still up by 4 percentage points from its poll in 2016.
