Twenty years ago, Americans hardly gave their Muslim neighbors a thought. Then came 9/11, and our opinions suddenly blossomed. Two decades later we may be past assuming that Muslims want to topple the American government, but other supposed givens -- that Muslims tend to be conservative, for instance -- have been challenged in a new poll that shows how rudimentary our understanding of American Muslims can be. Start with the finding in a new poll, commissioned by Emgage and Muslim Public Affairs Council, that Muslim Americans voted overwhelmingly for Joe Biden in 2020, with 86% support. Only 6% voted for Donald Trump.
