In Michigan, home to the nation’s largest Arab American communities, 13.3 percent of Democratic primary voters selected “uncommitted.” In Wisconsin, where Biden won in 2020 by roughly 20,000 votes, more than double that number signaled the same status. And in Pennsylvania, where the margin is expected to be just as razor-thin, about 60,000 people, including Shepperd, wrote in some version of not-Biden. All three states carry outsize importance in determining November’s winner.
